【摘要】 山城重庆的建筑用地开挖过程中，通常采用了直立切坡。文章讨论了对于这种典型的岩质边坡，现行支护设计时采用库仑土压力理论计算推力的不合理性，并提出了相应的改进办法，然后通过有限元、拉格朗日差分分析等数值模拟手段对重庆市建筑开挖边坡的稳定性程度、变形破坏方式以及支护处理措施进行了研究。更多还原

【Abstract】 More and more buildinges are constructed on the cutting deck of high slopes in the socall mountain city──Chongqing.To this typical rock slope of Chongqing , the authors indicatethat the supporting design which adopts the theory of Columbu soil pressure is irrational and present a modified method in this paper. Moreover,the state of stability,deformation and failure wayand supporting measure of cutting slopes are studied by FEM and FLAC (Fast Laurangian Analysis of Continua).更多还原
