有限土体基坑双排桩支护结构计算分析
摘要:紧邻已有地下室的深基坑支护工程,坑后土体宽度有限。分别采用有限元法和解析公式法分析了该条件下基坑双排桩支护结构变形特征和土压力分布情况。提出了此种情况下双排桩的简化土压力计算方法,并提出了弹性抗力法计算模型。通过监测数据对上述方法进行了验证。
Abstract:Deep excavation supporting engineering which is close to the existing basement structure, the width of ground is limited. The deformation characteristic and distribution of the earth pressure of retaining structure with double-row piles which has been effected by the basement have been analyzed by the method of FEA and the analytical formula. The simplified earth pressure's calculation method of double-row piles which is applicable to such situations has been proposed, the program has been made. Based on observation data, the rationality of the recommended computational model has been tested and verified.
