渗透力作用下基坑环形支撑体系空间受力分析

Spatial Force Analysis on Ring Beam Support System of Deep Excavation Under Seepage

大型深基坑支护是当今工程界的热点课题之一,其中环形支撑体系作为一种新的基坑支护形式,在某些空间受限的条件下可以发挥其独特的优势。本文通过考虑渗流效应的影响,建立三维有限元模型,分析基坑环形支撑体系的内力、变形,系统分析了基坑环梁支撑体系在考虑渗流效应下的受力变形特点,旨在为该类支护结构的应用提供理论分析。

Large-scaled deep excavation support is one of the hot issues in geotechnical engineering field. As a new support system, the ring beam support has its unique advantages under some space-constrained conditions. In this thesis, the views will be considered under establishing three-dimension finite elements with seepage effect. The force and deformation performances of the ring beam support system are analyzed systematically with seepage effect, to provide theoretical analysis for the application of this support type.
