【摘要】 采用平面应变线弹性有限单元法,对深基坑双排桩支护结构的内力和变形进行了数值分析,揭示了桩身及连梁刚度、桩长、排距、土体性质等各种因素对双排桩影响的规律,并分析了不同区域的土体加固效果与加固宽度、加固深度之间的关系,为双排桩的优化设计提供了参考依据。更多还原

【Abstract】 By means of 2D-Fintie Element Method, this paper analyzes the characteristics of internal force and lateral displacement of the retaining structure with double-row piles, and reveals the regularity of effect of several factors on this type of retaining structure, such as the rigidity of the piles and beams, the length of the piles, the distance between front and back row piles, the properties of soil. The relation between reinforcement efficiency and the width and depth of reinforcement in different soil areas is also presented. The conclusion can be used for the optimum design reference.更多还原
