区间盾构井结构设计力学分析

在沈阳地铁二号线南延线起点区间盾构井的设计过程中,考虑到其结构受力具有典型的空间特性,且目前常用的平面框架模型在准确性及精度上都将会给设计带来一定的偏差,因此建立了空间模型,对其进行整体受力计算分析,并对其重要组成构件,如框架梁、墙、柱在施工和使用阶段的受力特性进行深入对比和分析,提出了各结构构件在不同设计阶段的控制要点,并对本区间盾构井结构进行了合理、经济的设计。

Mechanical Analysis on the Structure Design of Interzone Shield Shaft

In the designing process of the interzone shield shaft in the beginning section of southern extension of Shenyang Metro Line 2,the structure stress of the interzone shield shaft has typical spatial characteristics and the current commonly-used plane frame may bring amount of deviation in accuracy.Taking these factors into consideration,this paper builds a space model,calculates and analyzes its overall stress.Furthermore,it compares and makes a deep analysis on the mechanical characteristics of important st...
