膨胀岩地区公路工程边坡人工坡率及变形破坏分析

摘要

Combining with the actual situation of Zhang-Shi highway,based on field investigation and related statistical maps,this paper counted the natural slope ratio under different slope height condition,combining with the recommended cutting slope ratio,proposed the determining method of artificial slope ratio in expansion rock area,also analyzed the influence of cracks to slope stability,pointed out that the crack located in slope rear had maximum influence to stability.%结合张石高速实际情况，根据现场调查和有关图件，统计了不同坡高情况下的自然坡率，结合规范推荐路堑坡率值，提出了膨胀岩地区人工边坡坡率的确定方法，同时分析了裂隙对边坡稳定性的影响，指出裂隙位于边坡后部时对稳定性的影响最大。
