摘要
为设计某段路基的滑坡防护方案,根据野外地质调绘确定主滑方向及滑动规律,利用钻探取样揭露了滑体、滑带、滑床及滑坡规模,从地质条件、地形原因、大气降水,以及路堑支护进行成因分析,并对滑坡进行定性及剩余下滑力稳定性评价,确定防护比选方案。对设计方案进行对比并提出了滑坡治理方案。
To design the landslide protection program of a roadbed,the main slip direction and sliding laws are determined according to the field geological survey.The sliding body,sliding belt,sliding bed lithology,inclination and scaleis exposed based on the drilling working.Two protection comparison programs are confirmed based on the analysis of engineering geology analogy and mechanical stability of the slope.The problems of two governance designings are concluded and analyzed.At last,the treatment measures are designed by considering all the factors.
