摘要
模拟填筑分层加载过程，采用非线性填筑土体与衬砌结构联合作用的有限元方法，确定涵洞衬砌周边土体压力及其分布规律。
The finite element method is adopted to simulate the earthfill load increment and the deformation related to nonlinear earthfill during construction of the concrete liner,in order to determine the earthfill load pressure and its distribution around the culvert,as well as to calculate the internal force in the liner.
