摘要
Abstract
Bedding slope is a common unfavorable geological condition in mountain highway construction.Due to the existence of weak structural layers,it has a more complex geological failure mode than ordinary slopes that is prone to instability under external force disturbance during construction.Therefore,in order to reduce the instability fail-ure,the effective preventive measures were taken in advance for the slope.Namely,the bedding slope of the sliding section was inverted to calculate the relevant parameters of the sliding body structural plane;Based on the calculat-ed structural plane parameters,the stability of the non-sliding section bedding slope was simulated and analyzed to determine the remaining sliding force required for slope support;Finally,the targeted preventive measures were proposed and implemented,which ultimately improved the stability of the slope.When a small range of failure oc-curs in the slope,the stability parameters can be simulated and obtained,the bedding slope be treated by this method;At the same time,it can provide reference for slope protection under the same geological conditions to avoid larger slope instability failure for a preventive role.关键词
