Analysis of the Supporting Effect of Double Row Piles Reinforcement
-
摘要: 在天津软土地区使用悬臂双排桩支护会产生较大位移，针对这一特点，提出双排桩桩间使用水泥土加固技术，并对此进行了计算分析。结果表明，对基坑的加固效果明显，基坑总体水平变形量减少近30%；双排桩桩顶水平位移减小近40%。Abstract: The use of cantilever double row piles would cause a larger displacement in Tianjin soft soil area. According to this characteristic, the paper reinforced the soil by cement between the double row piles and then maked the calculation analysis. The results indicated that the effect of reinforcement on foundation pit deformation was obvious. The horizontal displacement of the excavation reduced by 30 %. The horizontal displacement of the double row piles top decreased nearly 40 %.
