Embodiment Construction
[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0048] figure 1 It is a flow chart of a landslide body drainage method shown in the embodiment of the present application. The method can be used in a drainage device. The drainage device includes a plurality of drainage grooves. The method includes the following steps:
[0049]Step 101, obtain the first corresponding relationship of the total length of multiple drainage grooves, the angle between any one of the multiple drainage grooves and the horizontal plane, and the distance between any two adjacent drainage grooves on the landslide body.
[0050] Step 102, acquiring the parameters of the landslide mass.
[0051] Step 103: Determine the critical rainfall when landslide occurs on the landslide body according to the parameter...

The invention discloses a landslide mass drainage method, and belongs to the technical field of geological disaster prevention and control. The landslide mass drainage method comprises the steps of obtaining a first corresponding relation, obtaining parameters of a landslide mass, determining critical rainfall when landslide occurs on the landslide mass according to the parameters of the landslide mass, and obtaining the drainage capacity of any drainage channel in a plurality of drainage channels under the condition that the drainage capacity of any drainage channel is equal to the rainfall volume of a landslide area corresponding to any drainage channel, the total length of the drainage grooves is minimum, the target included angle between any drainage groove and the horizontal plane and the target distance between any two adjacent drainage grooves are obtained, and the drainage device is laid on the landslide mass according to the target included angle and the target distance. The problems that construction is difficult and the construction period is prolonged due to the fact that the drainage groove is too long in the construction process are solved, and the effects of being good in drainage effect, low in construction difficulty and short in construction period are achieved.
Description
technical field [0001] The application relates to the technical field of geological disaster prevention and control, in particular to a landslide mass drainage method. Background technique [0002] Landslide disaster is a serious natural disaster at present. Most landslides are triggered by rainfall, and rainwater seeps into the landslide body. The landslide body (landslide body can refer to a slope with landslide risk) is in a saturated state, and the physical and mechanical parameters of rock and soil are significant. decrease, leading to landslides. Therefore, it is necessary to discharge rainfall efficiently and quickly to reduce the occurrence of landslide disasters. [0003] At present, the following method is usually used for drainage: digging a plurality of parallel drainage grooves all over the landslide body at regular intervals on the surface of the landslide body, and introducing landslide drainage ditches or natural side ditches downstream of the drainage groov...
