将圆管及周围土体作为整体研究对象 ,采用有限单元法计算圆管涵的应力。研究了不同性质的填土作用对圆管应力的影响 ,指出了目前圆管结构计算中存在的问题 ,提出了采用刚性基座对圆管涵进行加固的方案 ,并给出了刚性基座的合理形式和尺寸。
The pipe and the surrounding soil are taken as the whole research object, and the finite element method is used to calculate the stress of the pipe culvert. The effect of filling with different properties on the stress of circular tube was studied. The existing problems in the calculation of circular tube were pointed out. The scheme of using rigid base to reinforce the circular tube and culvert was proposed. The rigid base Reasonable form and size.
