Description

Technical Field

[0001] The present invention relates to a landslide area monitoring and treatment method and system, in particular to a monitoring and treatment method and system for a loess-like soil landslide area where the sliding surface is softened by water. Background Art

[0002] Soil landslides are very common natural disasters, and the factors causing soil landslides are also diverse. The loess-like soil landslide disaster is a typical one among them.

[0003] The characteristics of the loess-like soil area are that when the loess-like soil meets water, it is prone to softening, resulting in a decrease in the mechanical strength of the soil mass, and thus a sliding surface is formed. Therefore, in the loess-like soil area, when rainfall or surface water infiltrates into the sliding surface, the mechanical strength of the soil mass on both sides of the sliding surface decreases, resulting in a decrease in the provided anti-sliding force, and a landslide disaster occurs under the action of gravity.

[0004] Currently, the monitoring of soil landslide disasters, including those in loess-like soil areas, mainly focuses on monitoring the surface displacement and deformation of the landslide body. By analyzing the development trend of the displacement and deformation, the sliding signs of the landslide are judged to achieve landslide monitoring. However, this kind of landslide monitoring can only provide early warning services and cannot truly dispose of and avoid landslide disasters. At present, the methods for disposing of and avoiding landslides often use artificial structures to provide sliding resistance, thereby preventing landslides. However, the construction scope of the artificial structures in this disposal method is wide, the engineering quantity is large, the professional requirements are high, and the cost is very high. It is only suitable for some special areas with high requirements and has not been widely promoted and applied. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a monitoring and treatment method and system for a loess-like soil landslide area where the sliding surface is softened by water. The method and system of the present invention have the characteristics of integrating monitoring and treatment functions, and have the characteristics of small construction area, small engineering quantity, low professional requirements, low cost, strong practicability, and being suitable for wide promotion and application.

[0006] One of the technical solutions of the present invention:

[0007] A monitoring and treatment method for a loess-like soil landslide area where the sliding surface is softened by water, comprising the following steps:

[0008] (1) Drilling holes on the landslide body, with the bottom of the hole on the sliding surface, and arranging a drilling hole at a certain interval, and there are several drilling holes;

[0009] (2) Taking the soil on the sliding surface through the drilling hole, and conducting mechanical strength tests with different water contents or soil pressures in the laboratory to obtain the mathematical relationship between the water content W i or the soil pressure Y i and the strength parameters, and setting this mathematical relationship in the landslide stability calculation module of the processing center;

[0010] (3) Meanwhile, several soil moisture sensors or soil pressure sensors are buried at intervals in the borehole, as well as several soil drying devices or soil microwave consolidation devices;

[0012] (5) The data collector collects these soil moisture or soil pressure data and transmits them to the processing center. The processing center calculates the stability coefficient of the landslide body. When the calculated stability coefficient is greater than the pre-set k value, the stability is better and the system does not need to perform the next action;
