摘要
城市浅埋隧道结构计算时通常简化为平面应变问题,采用荷载结构模型进行计算,但随着我国城市地下空间的进一步开发和利用,新建隧道受建设条件的限制,如避让既有地下建(构)筑物等,往往需采用较大的纵坡,而且这种情况越来越多,因此很有必要就纵坡对隧道结构的受力影响进行分析,为相关设计和施工提供参考。
In calculation of urban shallow tunnel structure,it is usually simplified as plane strain problem and calculated by load structure model. However,with further development and utilization of urban underground space in China,new tunnels that are limited by construction conditions,such as avoiding existing underground buildings,often need to use larger longitudinal slope,which is more and more common. Therefore,it is necessary to analyze influence of longitudinal slope on tunnel structure,so as to provide reference for relevant design and construction.
