双排桩支护结构设计参数优化
摘要:双排桩支护结构具有工期短、施工占地少、支护深度大等特点,因此得到广泛应用。但因为该结构体系受力较为复杂,设计计算理论尚不十分成熟,工程实践中也出现了一些问题,所以有必要对双排桩的设计参数进行深入研究,探索有效的改良方法。利用有限差分软件FLAC 3D建立数值分析模型,研究其受力及变形分布规律,进而对该支护结构提出优化改良的建议。
Abstract:The double row pile support structure has the characteristics of short construction period,small construction area and large supporting depth,so it is widely used.Because the stress is relatively complex of structural system,design and calculation theory is not very mature,some problems have been found in engineering practice,so it is necessary to conduct the thorough research to the design parameters of double row piles and to explore effective improvement method.In this paper,the finite difference software FLAC 3Dis used to set up the numerical analysis model to study its force and deformation distribution law,and then proposed the optimization and improvement measures for the support structure.
