考虑环境效应的悬臂桩排支护结构优化设计

OPTIMISTIC DESIGNING OF CANTILEVER PILE CLUSTERS WITH CONSIDERATION OF ENVIRONMENT EFFECT

采用ｍ 法，控制桩身最大变形，通过对给定基坑外地表最大沉降量情况下的悬臂式桩排支护结构进行优化设计，来考虑基坑开挖的环境效应。经工程验证表明，效果明显。

Given the largest subsidence of the ground beside the deep pit and controlling the largest horizontal deformation of piles with m-method,the optimistical design of cantilever pile clusters is put forward with the consideration of environment effect of excavation. The effect testified by projects is obvious.
