摘要
针对软土地基上加筋土路堤的工程特点,采用强度折减联合有限差分的方法,从安全系数和潜在滑动面两个方面入手,得出了软土地基上加筋土路堤不同时刻的稳定特性,并分析了加筋层数、填料内摩擦角及地基模量等参数对稳定的敏感性。研究结果表明,软土地基上加筋土路堤不同时刻的稳定特性不同,增大筋材层数、填料的内摩擦角及地基模量,软土地基上加筋土路堤的稳定性有所增加,但超过一定阶段后,其增加程度不再明显。研究成果对软土地基上加筋土路堤的实际工程应用有一定的参考作用。
According to the engineering characteristics of reinforced embankment on soft soil,the characteristics of stability of reinforced embankment on soft soil at different times are determined and the sensitivity of stability to layers of reinforcement,inner friction angle of stiffing,and module of ground are analyzed from two aspects of safety and potential sliding surface by means of strength reduction method and finite difference method.It is found that the more layer of reinforcement,the greater inner fricti...
