| 摘 要： | 将双排桩与水泥土连拱墙复合形成支护体系,共同工作,可起到止水和围护双重功效.采用三维有限元方法,针对双排桩复合连拱支护结构进行了受力变形性能的数值模拟.得出了连拱支护部分竖向、水平向传力的分配比例,以及双排桩部分前后排桩受力和变形特征.研究认为该复合支护结构内力分配均匀,受力合理,且对减小基坑侧移变形具有显著的技术优势,为深基坑工程提供了一种新的支护体系形式.

| Abstract: | The support system of double-pile and double-arch of soil-cement wall can work together and serve to seal and envelope. This paper is on the numerical simulation on the characteristics of deformation by the force against double pile and double-arch by 3-D finite element method. The vertical,horizontal-force distribution ratio in the arch support,and force and deformation characteristics of the double row pile pile can be drawn. Research that the supporting structure has significant advantages of uniform dis... |
