摘要
通过对寒区路堑人工土质边坡滑塌现象的调查研究,分析了人工路堑边坡滑塌的主要原因及影响因素,在此基础上构建寒区路堑人工边坡稳定性的力学模型,通过对春融期处于饱和状态的边坡土体稳定性进行验算,提出宜排水固坡不宜削坡稳定的寒区路堑人工土质路堑边坡稳定措施,即采用土工材料下层排水,利用网状土工格室上层固土并种植喜水根深的马莲草的综合边坡稳定技术,取得较为理想的防治效果。
It analyzes and puts forward main causes and influencing factors of artifical side slope slide of soil-cutting in frost area and forms a mechanical theoretical model. Based on checking computation of artifical side slope saturated soil stability in melting period, it provides effective measures by adopting drainage to stabilize side slope instead of cutting it to keep soil-cutting side slope stable in frost area, namely, the comprehensive stability technology of side slope by introducing geotextile as lower levels drainage and by adopting net geotextile lattice to stabilize soil and planting Malian grass.
