预应力地下连续墙研究概述

The Art - of - the-State of Prestressed Diaphragm Wall Study

通过相似模拟试验,对预应力技术应用到地下连续墙结构研究表明,可在墙体内建立起合适的预压应力、提高墙体的抗裂性和抗弯刚度、产生同外荷载作用反向的挠度,达到了减小墙体变形、提高耐久性、节约材料等效果。

Using presstressed technology in diaphragm wall structure can make appropriate pressure stress built up in the wall so that the ability of crack resistance and bending stiffness can be improved and reversed-direction of deflection opposite to outside-loading can be produced to reduce wall's deformation, heighten wall's durability and save constructional materials etc.
