综合管廊基坑支护工程中若干问题的探讨

在综合管廊基坑支护工程中,场地若无放坡条件,则优先考虑拉森钢板桩或SMW工法桩加内支撑的形式,造价较低,施工快捷,之后考虑钻孔灌注桩加内支撑的形式。文章以长沙某综合管廊基坑为例,从几方面探讨了几种支护形式的可行性。

In the foundation pit project of comprehensive pipe corridor, if the site has no conditions for grading, then we should give priority to the use of Larsen steel sheet pile or SMW method of pile with inner support, which cost less and facilitate construction. After that we consider the drilling pile with inner support. In this paper, with a pipe foundation in Changsha City as an example, we discuss the feasibility of several forms of support.
