顶管工作坑安全支护桩结构设计研究

摘要

本文以西安市东月路顶管工作坑为研究对象,通过对现场实测数据的分析,以及实测数据与有限元软件计算结果的对比分析,得出了黄土地区支护桩结构受力特点及桩后土压力分布规律.%Taking pipe jacking pit on Xi' an Dongyue Road as an example, the data measured on site were analyzed and compared with the result calculated by FEA software. The conclusion has been reached on the stressing characteristics of retaining piles in loess regions, and on the distributing characteristics of earth pressure on retaining piles.
