单支撑维护结构的土压力分析

Soil Pressure Analysis of One Layer Braced Structure

为了研究地连墙前型钢的受力性能及其使用情况下是否存在浪费现象,利用两种不同的计算方法,通过对天津文化中心三标段一部分地连墙单支撑支护结构的土压力进行分析,得出两种计算方法的结果,并计算出在静态情况下型钢所受力的大小。结果表明,型钢所受力小于其极限承载力,即型钢处于安全的工作状态,但型钢的使用也存在一定的浪费现象。

In order to study the work behavior of shaped steels and their waste when being used, we use two different methods, through analyzing the soil pressure of partial underground continuous walls in the third section of Tianjin Cultural Center, we get two calculating results, and then figure out the stress of the shaped steels in the static state. The result shows that the stress of the shaped steels is smaller than their ultimate bearing capacity, which means that the shaped steels are in safety and there is some waste in the process of their use.
