Description

Technical Field

[0002] In dike construction projects, hydraulic filling construction is a common filling method. Traditional hydraulic filling construction methods often lack scientific and effective means for monitoring and regulating the construction process. In terms of controlling the filling speed, a fixed construction speed is usually adopted, without fully considering the actual settlement of the soil during the filling process. This may lead to problems such as excessive settlement of the soil and instability of the foundation when the filling speed is too fast when the bearing capacity of the soil is insufficient; while when the soil conditions are good and the construction progress can be accelerated, a low filling speed is still maintained, affecting the construction efficiency.

[0020] Other advantages, objectives and features of the present invention will be partially reflected by the following description, and partially will also be understood by those skilled in the art through the research and practice of the present invention. Brief Description of the Drawings

[0021] Figure 1 It is a flow chart of the method for embankment hydraulic filling construction provided by the present invention. Detailed Embodiment

[0022] The following further elaborates the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0023] As Figure 1 shown, the present invention provides a method for embankment hydraulic filling construction, including:

[0024] Step 1. Monitoring point layout: Arrange multiple monitoring points in the reclamation area, and set a first settlement threshold and a second settlement threshold, where the first settlement threshold is greater than the second settlement threshold.

[0025] According to the geological conditions of the reclamation area, arrange multiple monitoring points evenly and reasonably in the reclamation area. For areas with complex geological conditions, such as areas with faults, uneven distribution of soft soil layers, and parts where large settlement differences are expected, such as the intersection of the dam edge and the center, the junction of different soil layers, etc., appropriately increase the density of monitoring points to ensure that settlement data can be obtained comprehensively and accurately. At the same time, in combination with the specific design settlement control standard of this project, set a first settlement threshold and a second settlement threshold, and ensure that the first settlement threshold is greater than the second settlement threshold.

[0026] Step 2. Reclamation construction and settlement calculation in the previous monitoring period: In the previous monitoring period, conduct reclamation construction on the reclamation area at the set reclamation speed; and measure the elevation values at each monitoring point at the start time and end time of the previous monitoring period respectively; calculate the settlement of each monitoring point in the previous monitoring period based on the elevation values at the start time and end time of the previous monitoring period; calculate the settlement of the reclamation area in the previous monitoring period based on the settlements of the multiple monitoring points in the previous monitoring period.

[0027] Use the formula (starting elevation minus ending elevation) to accurately calculate the settlement of each monitoring point in this monitoring period.

[0028] Step 3. Calculation of the reclamation speed in the next monitoring period: When the settlement of the reclamation area in the previous monitoring period is greater than or equal to the first settlement threshold, reduce the reclamation speed adopted in the next monitoring period to 70 - 80% of the reclamation speed adopted in the previous monitoring period; when the settlement of the reclamation area in the previous monitoring period is less than or equal to the second settlement threshold, increase the reclamation speed adopted in the next monitoring period to 1.1 to 1.3 times the reclamation speed adopted in the previous monitoring period; when the settlement of the reclamation area in the previous monitoring period is between the second settlement threshold and the first settlement threshold, keep the reclamation speed unchanged.

[0029] After the settlement amount of the hydraulic fill area in the previous monitoring period is calculated, it is compared with a preset first settlement amount threshold and a second settlement amount threshold. If the settlement amount is greater than or equal to the first settlement amount threshold, it indicates that under the current hydraulic fill speed, the load borne by the soil mass is too large, the settlement rate exceeds the safe range, and there is a risk of foundation instability. At this time, quickly reduce the hydraulic fill speed adopted in the next monitoring period to 70-80% of the hydraulic fill speed in the previous monitoring period. If the settlement amount is less than or equal to the second settlement amount threshold, it means that under the current hydraulic fill speed, the settlement rate of the soil mass is slow. On the premise of ensuring construction safety and quality, the construction efficiency can be appropriately increased. Increase the hydraulic fill speed adopted in the next monitoring period to 1.1 to 1.3 times the hydraulic fill speed in the previous monitoring period. If the settlement amount is between the second settlement amount threshold and the first settlement amount threshold, it indicates that the current hydraulic fill speed matches well with the bearing and settlement characteristics of the soil mass, and the soil mass settlement is stable and within the safe range. Keep the hydraulic fill speed unchanged in the next monitoring period.

[0030] Step Four: Repeat Step Two and Step Three, and carry out hydraulic fill construction on the hydraulic fill area at the corresponding hydraulic fill speed in multiple monitoring periods.

[0031] Continuously repeat Step Two and Step Three. In multiple monitoring periods, dynamically adjust the hydraulic fill speed according to real-time monitoring data, and carry out scientific and efficient hydraulic fill construction on the hydraulic fill area. For example, start construction from the 1st monitoring period, and its corresponding hydraulic fill speed is 0.1 m. After the hydraulic fill is completed, calculate the settlement amount of the hydraulic fill area in the 1st monitoring period; compare the settlement amount in the 1st monitoring period with the first settlement amount threshold and the second settlement amount threshold, and determine the hydraulic fill speed in the 2nd monitoring period according to the comparison result. Then carry out construction in the 2nd monitoring period at the determined hydraulic fill speed. And so on, until the construction is completed in the last monitoring period.

[0032] In summary, the present invention effectively avoids the problem of foundation instability caused by excessive settlement of the soil mass due to too fast hydraulic fill speed by real-time monitoring the settlement amount and timely adjusting the hydraulic fill speed according to the threshold, and improves the construction quality of the dike. Moreover, when the settlement of the soil mass is good, it can reasonably increase the hydraulic fill speed, avoid unnecessary low-speed construction, and greatly shorten the construction period and improve the construction efficiency on the premise of ensuring the construction quality.

[0033] In a preferred embodiment, in the dike hydraulic fill construction method, in Step Two, calculating the settlement amount of the hydraulic fill area in the previous monitoring period according to the settlement amounts of the multiple monitoring points in the previous monitoring period is achieved through the following process: calculating the average value of the settlement amounts of the multiple monitoring points in the previous monitoring period as the settlement amount of the hydraulic fill area in the previous monitoring period.

[0034] If the geological conditions in the hydraulic filling area are relatively uniform and the differences in the stratum structure and soil properties are small, the settlement of the hydraulic filling area in the previous monitoring period can be calculated as the arithmetic mean of the settlements of multiple monitoring points in the previous monitoring period.

[0035] In a preferred embodiment, in the described dike hydraulic filling construction method, in step two, calculating the settlement of the hydraulic filling area in the previous monitoring period based on the settlements of the multiple monitoring points in the previous monitoring period is achieved through the following process: The multiple monitoring points include one monitoring point set at the central position of the hydraulic filling area and other monitoring points set at the edge positions. Among them, a weight α1 is assigned to the monitoring point set at the central position, and a weight α2 is assigned to the other monitoring points set at the edge positions, where α1 is greater than α2. By performing weighted calculation on the settlement of the monitoring point set at the central position in the previous monitoring period and the settlements of the other monitoring points set at the edge positions, the settlement of the hydraulic filling area in the previous monitoring period is obtained.

[0036] If there are obvious differences in geological conditions and the soil properties and bearing capacities at different positions in the hydraulic filling area are different, corresponding weights can be assigned to the monitoring points at different positions (for example, the weight of the monitoring points in the central area is higher than that in the edge area, and the weight of the monitoring points in special geological areas is determined separately), and the weighted average method is used to calculate the settlement of the hydraulic filling area to more accurately reflect the overall settlement of the hydraulic filling area.

[0037] In a preferred embodiment, in the described dike hydraulic filling construction method, the multiple monitoring points further include monitoring points set at uneven soil layer positions. A weight α3 is assigned to the monitoring points set at uneven soil layer positions, where α3 is greater than α2. By performing weighted calculation on the settlement of the monitoring point set at the central position in the previous monitoring period, the settlements of the other monitoring points set at the edge positions in the previous monitoring period, and the settlements of the monitoring points set at uneven soil layer positions in the previous monitoring period, the settlement of the hydraulic filling area in the previous monitoring period is obtained.

[0038] For complex geological areas, corresponding weights are assigned to the monitoring points at different positions according to the importance and geological characteristics of the positions where the monitoring points are located. For example, the weight of the monitoring points in the central area is α1, the weight of the monitoring points in the edge area is α2, and the weight of the monitoring points in special geological areas is α3 (α1 > α2, and α3 is determined according to the specific geological conditions). The weighted average method is used to calculate the settlement of the hydraulic filling area to more accurately reflect the overall settlement of the hydraulic filling area.

[0039] In a preferred embodiment, in the method for embankment hydraulic fill construction, when the settlement amounts in the continuous n monitoring periods of the hydraulic fill area are all between the second settlement amount threshold and the first settlement amount threshold, the (n + 1)-th monitoring period is extended to 2 to 3 times that of the n-th monitoring period, where the first monitoring period is set to 1 day.

[0040] A higher monitoring frequency can obtain settlement data more timely and accurately. For example, at the initial stage of hydraulic fill construction, settlement monitoring is carried out every day, and the deformation of the soil body under the action of the new load can be accurately grasped. If it is found that the settlement rate is too fast, it can provide a basis for reducing the hydraulic fill rate. When the hydraulic fill construction reaches a certain stage, the soil body gradually adapts to the new load and the change is relatively stable. The settlement monitoring can be carried out once every 2 - 3 days. This adjustment mechanism helps to further observe the long-term settlement trend of the soil body when the construction state is stable, reduce unnecessary frequent monitoring, and optimize the allocation of construction resources.

[0041] In a preferred embodiment, in the method for embankment hydraulic fill construction, when the change range of the settlement amounts in the continuous n monitoring periods of the hydraulic fill area is less than 10% of the set change range threshold, the (n + 1)-th monitoring period is extended to 2 to 3 times that of the n-th monitoring period, where the first monitoring period is set to 1 day.

[0042] A higher monitoring frequency can obtain settlement data more timely and accurately. For example, at the initial stage of hydraulic fill construction, settlement monitoring is carried out every day, and the deformation of the soil body under the action of the new load can be accurately grasped. If it is found that the settlement rate is too fast, it can provide a basis for reducing the hydraulic fill rate. When the hydraulic fill construction reaches a certain stage, the soil body gradually adapts to the new load and the change is relatively stable. The settlement monitoring can be carried out once every 2 - 3 days. This adjustment mechanism helps to further observe the long-term settlement trend of the soil body when the construction state is stable, reduce unnecessary frequent monitoring, and optimize the allocation of construction resources.

[0043] In a preferred embodiment, in the method for embankment hydraulic fill construction, for fine-grained soil, the hydraulic fill speed adopted in the first monitoring period is 0.1 to 0.2 meters per day; for coarse-grained soil, the hydraulic fill speed adopted in the first monitoring period is 0.2 to 0.4 meters per day.

[0044] During the process of hydraulic fill construction, considering the soil quality factors is also necessary for controlling the hydraulic fill rate. Specifically, for fine-grained soil, the hydraulic fill speed adopted in the first monitoring period is 0.1 to 0.2 meters per day; for coarse-grained soil, the hydraulic fill speed adopted in the first monitoring period is 0.2 to 0.4 meters per day. For coarse-grained soil, such as sandy soil and gravel soil, etc., the water permeability is good and the drainage consolidation speed is fast, and the hydraulic fill rate can be appropriately increased. However, problems such as slope instability caused by too fast hydraulic fill should also be avoided. Generally, the daily hydraulic fill thickness can be controlled at about 0.2 - 0.4 meters.

[0045] In a preferred embodiment, in the method for embankment hydraulic fill construction, the hydraulic fill area is set as a rectangular area, and the multiple monitoring points include one monitoring point arranged at the center position of the rectangular area, four monitoring points arranged at the four vertices of the rectangular area, and / or monitoring points arranged at the positions with uneven soil layers in the rectangular area.

[0046] Settlement monitoring points are arranged at certain intervals and layouts within the hydraulic fill area and a certain range around it. Generally, monitoring points should be densely arranged in the central area, edge area of the hydraulic fill area, and areas where geological conditions may change. For example, for a large rectangular hydraulic fill area, monitoring points can be arranged at its center and four vertices, and also at the midpoints of the long side and the short side to comprehensively grasp the settlement situation of the hydraulic fill area.

[0047] In a preferred embodiment, in the method for embankment hydraulic fill construction, the first settlement threshold is set to 5 to 10 millimeters per day, and the second settlement threshold is set to 2 - 3 millimeters per day.

[0048] Although the embodiments of the present invention have been disclosed as above, they are not limited to only the applications listed in the description and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated and described examples here.
