高陡顺向岩质人工边坡治理研究

Research on control and treatment of hingly artificial bedding rock slope failure

在工程地质评价基础上,应用数学力学模拟方法进行切坡稳定性定量评价.结合切坡特点,对深层结构面采用推力传递系数法进行稳定性计算,基本荷载仅考虑岩体自重,组合荷载包括重力、静水(渗水)压力和地震力的组合作用.该切坡是由破碎岩体的块状多次多向块体滑移与深层层面滑移结合的破坏模式.考虑局部滑移与整体滑动的危险,暴雨与风化作用下,边坡变形破坏可能进一步发育,提出预应力锚索+地梁的措施进行治理是合适的.

On the basis of evaluation of geological engineering,the stability of the cutting slope was quantitatively evaluated using geological mathematics mechanics method.According to the characteristic of the slope,the stability of the deep structural plane is calculated by means of transmission coefficient：Considering the dead-weight of the rock mass as the basic load and the assembled operation of dead-weight,hydrostatic pressure（exudation-pressure）,seismic force as combined load.The mode of slope failure comsists of massive slippage in multiway on many occasions and bedding slip of deep surface.Considering the danger of local and whole failure,and the function of the rainstorm and efflorescence,the control and treatment of artificial rock slope should take prestressed anchor-rope and ground beam measure.
