基于表面与深部位移相协同的滑坡分级预警方法
Landslide classification warning method based on coordination of surface and deep displacement
摘要
Abstract
Aiming at the issues of low accuracy,high repetition rate,and non-universality of the landslide classification early warning method,based on the statistical characteristics of displacement evolution during the landslide process and the principle of normality test,a method for slip surface advance identification and landslide classification early warning based on surface displacement and deep displacement information was established.The normality tests of surface displacement velocity,surface displacement acceleration,and deep displacement dislocation momentum were carried out to determine the three-level early warning times of landslide start-up,landslide acceleration,and landslide rapid acceleration.The accuracy of the three-level early warning times and the rationality of the inferred position of the slide surface were verified through engineering examples.The research results can enrich the theory and method of landslide warning,enhance the warning precision,and provide references for the design of open-pit slope engineering.关键词
