综合管廊交叉口中隔壁板对框架受力影响分析

摘要:

综合管廊的交叉口节点是一个典型的三维受力节点,不同于标准断面设计的单向截条设计法,交叉口节点需要建立三维模型计算,同时需要分两个方向取单向框架进行复核。本文以某工程交叉口为例,着重分析交叉口中隔壁板对单向框架受力的影响,从而对相关工程起到一定的借鉴作用。

Abstract:

The intersection node of utility tunnel is a typical three-dimensional stress node. The intersection node needs to establish a three-dimensional model for calculation, which is different from the one-way strip design method of standard section design, at the same time, it needs to take one-way frame from two directions for review. Taking an engineering intersection as an example, this paper focuses on the analysis of the intersection about the influence of the middle wall on the frame stress, so as to provideSaSreference for related projects.
