The invention discloses a stability rating method for the damage risk analysis of an excavated rock slope, and the method comprises the steps: carrying out the field in-situ test of the excavated rockslope, and obtaining the rock mass quality parameters of the slope; acquiring three-dimensional modeling and data coordinates of the excavated rock slope according to the image shot by the unmanned aerial vehicle to obtain structural plane parameters of the slope to be measured; identifying and calculating key block bodies of the excavated rock slope to obtain the block body volume and the blockbody number; formulating an excavated rock slope stability grading table; constructing a multi-factor abrupt change stage excavation rock slope rating hierarchical analysis parameter model; and according to the multi-factor abrupt change stage excavation rock slope rating hierarchical analysis parameter model, calculating an abrupt change value of the to-be-measured slope, and realizing calculation of an excavation rock slope stability evaluation value and stability rating of a corresponding slope. The method is high in realizability, the problems that a traditional evaluation method is largein limitation, low in evaluation precision, complex and the like are solved, multiple factors are considered, and high reasonability and evaluation precision are achieved.
Description
technical field [0001] The invention relates to a stability research technology for mountain slopes, in particular to a stability rating method for risk analysis of excavated rock slope damage. Background technique [0002] With the emergence of global climate anomalies and frequent geological disasters, the environmental and safety issues caused by engineering geological disasters have attracted people's attention. In the process of on-site construction, on the one hand, in order to expand the scale of the project, and on the other hand, due to the limitation of the site, it is often necessary to excavate different types of slopes under complex geological conditions. The stability of slope engineering is directly related to engineering construction, which has an important restrictive effect on the safety, feasibility and economy of the engineering, and affects the investment and benefits of engineering construction to a large extent. However, the increasingly prominent lan...
