| 摘 要： | 在对双排桩现有研究的基础上，综合考虑桩土效应，并实现对双排桩的三雏数值模拟。针对双排桩的几个参数进行了在不同的工况下对双排桩进行的分析。分析结果表明：（1）双排桩支护体系空间效应显著；（2）双排桩相对于单排桩表现出更好的支护性能；（3）排距、桩径对双排桩的性状特点影响较大。 |

| Abstract: | Based on the current research status of the double-row piles,this paper makes three-dimensional numerical simulate come true by considering the pile-soil interaction synthetically.Aimed at several parameters of the double-row piles,this paper makes conclusion by analyzing the double-row piles under different construction condition: 1.double-row-pile has a marked spatial effect.2.double-row-pile has a better performance at foundation pit support than single-row-pile.3.the interval between double-row piles and the diameters of the piles have great effects than the performance of double-row-pile. |
