【摘要】 为研究相邻基坑间堆载情况下的变形特点,利用岩土有限元软件PLAXIS 3D Foundation进行数值模拟,计算和分析结果表明:当相邻两基坑为悬臂式或支撑式支护结构,且基坑间距不同时,基坑支护结构水平位移、基坑间地面沉降以及基坑底隆起存在规律性。并且通过工程实例,对基坑变形规律进行了验证。更多还原

【Abstract】 In order to study the deformation characteristics in the presence of heaped load cases between foundation excavation,the geotechnical finite element software PLAXIS 3D Foundation numerical simulation is conducted.Calculation and analysis results show that:when the adjacent excavations are cantilever retaining structure or support retaining structure,and the adjacent excavations are not the same distance,horizontal displacement of foundation retaining structure,land subsidence between foundation excavation and bottom uplift exist regularity.By an engineering example,deformation regularity of foundation excavation is verified.更多还原
