Slope stability evaluation method and device

Abstract

The embodiment of the invention provides a slope stability evaluation method and device, and belongs to the technical field of land engineering. The slope stability evaluation method comprises the following steps: determining an investigation area needing slope stability evaluation; obtaining historical information of each side slope in the survey area, and determining a target side slope of whichthe stability needs to be evaluated in the survey area based on the historical information of each side slope; and determining the stability index of each target slope according to the actual exploration information of each target slope. According to the method provided by the embodiment of the invention, the survey area needing slope stability evaluation is determined; the historical informationof each slope in the survey area is acquired; the target slope needing stability evaluation in the survey area is determined based on the historical information of each slope; the stability index ofeach target slope is determined according to the actual exploration information of each target slope; and due to the fact that only the stability index needs to be obtained, the stability of the slopecan be evaluated, so that the efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of land engineering, in particular to a slope stability evaluation method and device. Background technique [0002] Ecological projects such as returning farmland to forest (grassland) on the Loess Plateau transform slope farmland into ecological land such as woodland or grassland, and shift agricultural production in the Loess Plateau from slopes to ditches. In recent years, ditch control and land reclamation projects have effectively supplemented the area of ​​cultivated land and eased the conflict between man and land in the Loess Plateau. However, the slope cutting measures of the ditch control and land reclamation project produced a large number of excavated slopes, and the alternate arrangement of slopes and setbacks reduced the slope to a certain extent, and vegetation such as shrubs and grasses effectively alleviated soil erosion. However, instability problems such as excavation slope collapse and l...

Problems solved by technology

[0003] At present, the main methods of slope stability investigation in the Loess Plateau area include indoor simulation and field investigation. There are certain differences between the indoor simulated environment and the actual climate conditions, and the applicability of the results is weak; engineering drilling, geophysical detection, and mechanical tests Field investigation methods such as field surveys are time-consuming, laborious, and costly, and it is difficult to quickly and accurately obtain the stability of a large number of slopes.
