    • Abstract
  • Because of its simple method, convenient construction and good anti sliding effect, deloading through rock and soil removal is one of the commonly used measures for landslide control. But different cutting position has different effects on the stability of a slope. In order to illustrate intuitionally this kind of influence, this paper learns from the concept of the influence line of moving load in structural mechanics. By reducing load in different position as the variable load and reducing load to each case corresponds to the stability coefficient as the value of influence, the analysis method for the influence line of the load reduction on the landslide was put forward. According to the size of the stability factor and combined with the engineering practice, the optimal cutting position of the landslide was determined. Finally, taking a landslide as an example, statistics were made for the stability factor corresponding to deloading through rock and soil removal at different position. According to the size of the coefficient of stability and combined with the situation of the slope, the optimal unloading position was given, which provides the basis for the reasonable and scientific load reduction. The method is simple in calculation and the result is clear and direct, can provide reference for similar landslide treatment engineering.
