Description

Technical Field

[0001] The present invention relates to the field of BIM technology, and in particular to a BIM-based anti-slide pile model generation method and a construction method. Background Art

[0002] Anti-slide piles are engineering structures primarily used to enhance the stability of slopes or side slopes, preventing landslides and soil instability. They can be single, double, or multiple piles, and are sometimes used in conjunction with other retaining structures (such as retaining walls and anchors). Design considerations include geological conditions, soil type, slope, and loads (such as those caused by earthquakes and rainfall).

[0003] When carrying out anti-slip pile construction, the anti-slip piles of a project are characterized by a large number, great construction difficulty, great construction period pressure and high quality requirements.

[0004] The invention patent with application number: CN202311689634.8 discloses a construction method for a combination of channel slope concrete replacement and anti-slide piles. The method includes: without changing the top and toe lines of the channel slope, the area with rich weak interlayer development in the channel slope is reinforced with a combination of concrete replacement and anti-slide piles, and the concrete replacement amount and anti-slide pile construction parameters are reasonably determined to achieve the purpose of comprehensively improving the anti-slide stability requirements of the channel slope. The above method is based on the strength reduction method. By reducing the strength parameters of the channel slope body and the weak interlayer, the concrete replacement ratio and the anti-slide pile bearing coefficient are introduced, and the two are combined to form a variety of working conditions and the corresponding safety factors are calculated. From the perspective of construction difficulty and economy, the combination scheme of concrete replacement amount and anti-slide pile parameters is comprehensively determined to complete the reinforcement construction of the channel slope.

[0070] The embodiment of the present invention provides a method for generating an anti-slide pile model based on BIM, such as Figure 1 Shown, including:

[0071] Step 1: Obtain a slope support engineering plan for the earthwork filling process. The earthwork filling process is the process of changing the original terrain through excavation, transportation, and filling of earth and rock materials in a construction project.

[0076] In one embodiment, step 1: obtaining a slope support engineering plan during earthwork filling, includes:

[0077] During the earthwork filling process, the necessity analysis of slope support is carried out. The necessity analysis of slope support is to analyze whether slope support is necessary by considering factors such as geological conditions, slope and soil stability.

If the analysis shows it is necessary, the target slope is determined and its slope characteristics are extracted. Based on the slope characteristics, a slope support engineering plan is determined, thereby improving the rationality of the slope support engineering plan.

[0083] In one embodiment, a slope support engineering plan is determined based on the slope characteristics of the target slope, including:

[0084] Perform slope feature clustering on the slope features to obtain slope feature clustering results; wherein, slope feature clustering refers to grouping slopes with similar features into one category;

[0085] Determine at least one first retaining platform based on the clustering results of the slope characteristics; wherein the first retaining platform is: a slope with similar characteristics;

[0086] Traverse each first support platform in turn, use the first support platform being traversed as the second support platform, and use the slope characteristics corresponding to the second support platform as the basis for formulating the first slope support engineering plan for the second support platform;

[0103] Determining a second simulation result based on the instability factor simulation parameter and the first simulation result; wherein the second simulation result is: a simulation result of the corresponding simulation model after applying the interference of the instability factor simulation parameter on the first simulation result;

[0104] If the second simulation results meet the simulation expectations, the target plan is determined based on the specifications and positions of the third anti-slide piles and the second anti-slide pile support points. Otherwise, the second simulation results are attributed and the specifications and positions of the third anti-slide piles and the second anti-slide pile support points are adjusted based on the attribution results. The target plan is then determined based on the adjusted specifications and positions of the third anti-slide piles and the second anti-slide pile support points. Meeting the simulation expectations means that the third support platform does not collapse, suffer from significant soil erosion, or otherwise fail to meet construction standards.

If there is a similarity, the target plan can be determined based on the same logic as the corresponding second slope support engineering plan. Otherwise, the anti-sliding pile support strategy formulation model is trained based on the anti-sliding pile support record; the third anti-sliding pile specification parameters and the second anti-sliding pile support point are determined according to the available second anti-sliding pile specification parameters and the second support platform, and a simulation platform for the construction project is introduced to simulate the anti-sliding pile simulation entity supporting in the third support platform. After the simulated support, simulation data of environmental factors that affect the stability of the second support platform are also introduced to determine the support effect; when the support effect meets expectations, the target plan corresponding to the simulation strategy is output, otherwise adaptive adjustments are made to improve the rationality of the target plan formulation.

[0137] The working principle and beneficial effects of the above technical solution are:

[0138] The present invention obtains the local anti-slip pile model of the construction area that the construction worker is responsible for.

[0141] Based on the center of the area and the boundary point where the construction workers arrive, a look vector is constructed and used to instruct the construction workers. The direction of the look vector is the direction from the boundary point where the construction workers arrive to the center of the area.

[0142] The working principle and beneficial effects of the above technical solution are:

[0143] After the construction workers arrive at the actual position corresponding to the boundary point of the area, there is a situation where the observation line of sight does not fall into the area to be observed. Therefore, according to the center of the area circle and the boundary point of the area arrived by the construction workers, a viewing vector is constructed, and the vector angle is calculated based on the current viewing vector of the construction workers and the viewing vector, prompting the construction workers to adjust their line of sight, further improving the display efficiency.
