型钢水泥土搅拌墙在基坑工程中有着广泛的应用,但现有的实验室方法研究型钢水泥土梁强度时没有考虑到型钢所受约束作用对型钢水泥土梁强度的提高,导致型钢水泥土的经济效益无法完全展现。为了研究型钢的约束作用对搅拌墙的影响,本文设计了多组型钢受约束作用的组合梁与不受约束作用的组合梁对比试验,通过比较实验组与对照组梁的刚度变化曲线,得出约束作用对型钢水泥土搅拌墙产生影响的结论。本文对型钢水泥土搅拌墙的现场应用具有一定参考价值。
Steel-concrete mixing wall has a wide range of applications in foundation pit engineering. However, the existing laboratory methods to study the strength of steel-concrete beams do not take into account that the restraining effect of shaped steel on the strength of the steel- The economic benefits can not be fully demonstrated. In order to study the effect of confined steel beam on the mixing wall, this paper designed a multi-type steel constrained beam and unrestrained composite beam comparative test by comparing the experimental group and the control beam beam stiffness curve obtained Constraints on the impact of steel reinforced concrete mixing wall. This article has some reference value for the field application of the profiled cement-soil mixing wall.
