摘要
隧道开挖对邻近桩基工程影响的问题引起了国内外诸多学者关注。在概述目前研究成果的基础上,探讨了采用有限差分数值模拟技术模拟建筑物桩基的方法以及参数取值问题,并就北京某地铁隧道近距离穿越某桩基工程进行了模拟,分析了隧道开挖施工而引起周围土体及桩基的变形特点。其结果可为地铁建设中预测地铁开挖对于周围环境的影响提供参考。
More attention is focused on the problem of tunneling passing across the adjacent pile foundation. On the basis of a study of the current research findings,the method and parameter determination of numerical simulating on pile foundation are discussed . A case history that the tunnel was constructed through the adjacent pile foundation in Beijing is simulated,and deformation characteristics of surrounding ground and neighboring piled foundations caused by tunnel excavation are analyzed. The research results can be served as a reference to predicting the influence on the surrounding environment by tunnel excavation.
