Abstract

The invention discloses a treatment method for sliding of a high slope of fragmented bulk solid on the surface layer of a deep-layer strong-dumping deformation body, and relates to the field of slopeengineering. The technical problem to be solved is to provide a high-safety-risk and short-construction-cycle treatment method for sliding of the high slope. By means of the technical scheme, the treatment method for sliding of the high slope of the fragmented bulk solid on the surface layer of the deep-layer strong-dumping deformation body includes the steps of firstly, performing quick slag filling and reversely pressing the foot of the slope, restraining excessive deformation of the slope, and preventing deep-layer landslide; then, setting slope deformation temporary monitoring points, andconstructing a slope construction road; restraining loose deformation of the top of the slope through fore shaft anchor rods; cutting the slope and reducing the load to eliminate the source of dangeron the top of the slope; and finally, supporting the slope, wherein grouting is performed on broken rock mass on the surface layer of the slope through slope surface anchor rods according to the characteristic that the dumping deformation broken rock soil can be injected so that the loose broken rock can coagulate to have a bearing capacity. The method is suitable for sliding of the slope with thestrong-dumping deformation body on the deep layer and the fragmented bulk solid on the surface layer.

Description

technical field

[0001] The invention relates to the field of slope engineering, in particular to a treatment method for high slope landslides. Background technique

[0002] Toppling is a type of failure of slopes, which mainly occurs in slopes with anti-dipping layered structures, and is generally concentrated on river bank slopes. The basic types of slope toppling deformation include the following three types:

[0003] 1. Slope shallow toppling deformation-destruction, this type of slope toppling refers to the situation that the deformation of the rock mass slope is relatively small, and the rock layer will also topple. The main characteristics of this type of deformation are as follows:

[0004] First, this type of deformation generally occurs in places with relatively steep terrain, as well as mountain ridges formed by bank slopes cut by transverse gullies and nearby locations. In the canyons on the east side of the Qinghai-Tibet Plateau, this kind of toppling deformati...
