| 摘 要： | 介绍了两类计算填土涵顶附加压力的方法,即Boussinesq法和分布角法,结果表明：土体自重压力是随涵顶填土高度的增加而增加,而机械车辆附加压力随涵顶填土高度的增加而减小,Boussinesq法适用于填土较高的涵洞,分布角法适用于填土较低的涵洞。

| Abstract: | The paper introduces two kinds of calculation of the additional pressure of the filled culvert top,that is Boussinesq method and the distributing angle method,and proves by the results that the gravity pressure of the earth body increases with the addition of the filled height of the culvert top,while the additional pressure of the mechanical vehicle reduces with the increase of the filled height of the culvert top,so the Boussinesq method can be applied in the culvert with taller filled height,while the distributing angle method be applied in the one with lower filled height. |
