基于双侧非对称破坏模式的临坡地基极限承载力分析OA北大核心CSTPCD
Analysis on Ultimate Bearing Capacity of Ground Foundation Adjacent to Slope Based on Bilateral Asymmetry Failure Mode
在工程建设领域,经常需要把条形基础设置在临坡地基上,但在现行成果中,对临坡地基极限承载力的确定没有给出具体计算方法.建立双侧非对称滑移破坏模型,将坡后土体强度进行折减,用发挥系数m来表征其强度.基于极限平衡法和叠加原理,求得三个承载力系数的表达式.基于极限分析法原理,推导出临坡地基极限承载力上限解.采用离心模型试验对理论分析结果进行验证,并就条形基础作用下的临坡地基变形破坏特征以及基底接触条件、基础位置、边坡高度等诸多因素对临坡地基极限承载力的影…查看全部>>
In the field of engineering construction, foundations were often placed adjacent to slopes. In the present research work, the evaluation of the maximum bearing capacity of slope foundations lacked a sufficient-ly accurate method. A bilateral asymmetry slip failure model for ground foundation adjacent to slope was devel-oped, the strength of soil on the side of flat ground was reduced and this is characterized by a mobilization fac-tor. Base on limit equilibr…查看全部>>
