| 摘 要： | 提出了一个分析深基坑围护墙与支撑体系相互作用的新的计算模型,即把整个深基坑周边围护桩结构简化为空间杆系有限元体系,将支撑体系视为子结构,通过子结构凝缩与拼装方法分析围护桩与支撑体系的共同工作.该方法能够分析支撑体系的空间效应以及由支撑平面框架连接而产生的桩与桩之间的空间作用,能够分析实际工程中存在的不均匀开挖所带来的对支护结构变形和内力的影响,以及深基坑切向平面内支护结构的变形和内力等.最后,文章给出了一个均匀开挖的算例.

| Abstract: | A new calculation model for analyzing interaction between retaining wall and bracing system is proposed, which takes all retaining piles of deep excavation as spatial FEM system and regards bracing system as substructure with analyzing interaction between retaining wall and bracing system by the method of assembling sub-structure. This method can be used to analyze the space effect of supporting structure of deep excavation, the space effect of piles connected by bracing system, the influence of excavation uniformity on internal force and deformation in supporting structure and internal force and deformation of retaining structure in tangential plane and so on. Finally, an example with considering the excavation uniformity is analyzed. |
