摘要
以武汉市某深基坑为研究对象,先对该基坑支护结构的整体稳定性、抗倾覆、抗隆起进行计算,再用ABAQUS有限元软件建立了基坑数值模型,模拟分析了基坑在开挖过程中发生的水平变形、边坡沉降、坑底隆起以及支护桩变形等。通过计算与模拟的结果的对比,该基坑采用的单排支护桩+两道临时钢筋混凝土支撑的支护方案是安全稳定的。
Urban villages renovation project in Wuhan Yao Jialing K3 block foundation pit as the research object, the overall stability of the foundation pit supporting structure first, calculating the overturning resistance, resistance to uplift,to foundation pit numerical model was established with ABAQUS finite element software, simulation analysis of the foundation pit in excavation, slope sedimentation occurred in the process of horizontal deformation, uplifts and retaining pile deformation, etc. By comparing the results of checking and simulation, it is found that the support scheme of single row supporting pile and two temporary reinforced concrete bracing is safe and stable.
