天津港务局综合业务楼深基坑支护与监测

Design and monitoring of deep foundation pit in Tianjin port office multiple building

摘要: 介绍天津塘沽软土地区一个深１０．６ｍ采用单道环梁支撑的基坑工程设计与监测实例。计算采用弹性抗力法，并对土压力、水压力、支护结构变形、支撑系统变形以及周围地表沉降等项目进行了观测。通过计算与实测，对土压力分布、水土分算、水土合算、土的蠕变对变形的影响等进行了分析，得出一些有价值的结论。

Abstract: A 10.6 m deep foundation pit in the soft clay area of Tianjin, using single strut system, was given as an example. The elastic reaction method was used in calculation. The paper also gives some measured results including: soil and water pressure, deformation of retaining structure and strut system, the settlement of surrounding ground ,etc. Through comparing , some useful conclusions were obtained.
