| 摘 要： | 从加筋土体的等效围压概念出发,根据加筋土体发生拉裂破坏和剪切破坏时筋材所发挥的作用不同,提出了两种破坏形式下考虑等效围压折减系数的等效围压表达式,并根据加筋土体的极限平衡条件,确定了加筋土体的强度参数,分析了不同排水条件对加筋土体强度参数的影响。结合临界围压,建立起加筋土体强度破坏标准。按照一般加筋土体的广义等效围压,给出了两种破坏形式下等效围压折减系数的确定方法,并用实例进行验证。

| Abstract: | Base on equivalent confinement pressure and according to the different functions of the materials when the reinforced soil is pull or cohering to failure,the formula of equivalent confining pressure is carried out in the two failure models in which it is abated and the strength parameters are decided,the affect of drainage on the strength is also analyzed.So that the failure standard of strength of reinforced soil is set out in which the critical confining pressure is used.By the way,abating coefficient of ... |
