| 摘 要： | 本文采用平面应变非线性弹性有限单元法，编制了分析双排桩式围护结构的程序，藉此研究了软土地基中双排桩式围护结构的内力和变形特性．文章探讨了桩身刚度、土体性质、前后排桩排距、被动区土体加固对围护结构内力和变形的影响；并由此得到了双排桩式围护结构设计及施工的一些有益结论．

| Abstract: | A 2D-finite element Program is developed for analysis of behaviour of retaining structure of the double-row piles in this paper.The characteristies of internal force and lateral displacement of this type of retaning structure on soft soils are analysed,The effects of the rigidity of the piles and beams,the properties of soil,the distance of the double-row piles,the reinforcement of the passive area on internal force and lateral displacement of the retaining design are given. |
