《上海排水管道通用图》中采用管枕基础的管道内力分析

Internal Force Analysis of Pipe Based on Bearing Block in General Map of Shanghai Drainage Pipe

《上海排水管道通用图》(PASR-D-01-92),对于钢筋混凝土管道采用了管枕基础,现有规范没有对应的内力计算系数。本文基于平面有限元和三维有限元方法,对采用管枕基础的管道结构进行了内力分析,并结合管道施工过程中竖向荷载的分担比例,得出了采用管枕基础的管道设计的内力计算系数表。

In General Map of Shanghai Drainage Pipe(PASR-D-01-92),bearing block was adopted under RC pipe,but there is no corresponding coefficient of internal force calculation in existing specifications.Using plane finite element and 3 D finite element methods,this article analyzed the internal force of pipe structure based on bearing block.Considering vertical load share ratio between bearing block and sand and gravel foundation in the construction process,the design table of internal force calculation coefficient of pipe based on bearing block was obtained.
