| 摘 要： | 针对目前地下结构地震土压力设计方法的研究现状,介绍了计算挡土墙地震主动土压力的物部·冈部公式及浅埋隧道谢家然围岩压力理论。并结合物部·冈部公式、谢家然理论提出了一种适用于计算地下结构地震土压力的新方法。该方法基于极限平衡理论,根据谢家然理论提供的滑裂面参数构造了滑动土体,采用物部·冈部公式计算了滑动土体作用在地下结构边墙上的地震土压力。最后结合工程实例,将本文方法与其它计算方法进行了比较,评价了该计算方法的优缺点。

| Abstract: | The development of the seismic active pressure designs of underground structures was first briefly introduced,followed by introduction of Xie theory and M-O formula.Then a new method was put forward,which combined Xie theory and M-O formula.Based on limit equilibrium theory,this method constructed sliding soil according to sliding surface parameters of Xie theory,which could also be used for calculating the seismic active pressure of underground structures through M-O formula.Finally,in one practical example,brief evaluation and analysis of this new method were given through comparing to other design methods. |
