软土地区近接桩基深基坑现场监测方法与应用

摘要

在临近既有桩基深基坑开挖过程中，为了保证深基坑本身和既有桩基的安全，需要对深基坑和既有桩基变形进行监测。本文基于某软土地区近接既有桩基深基坑现场监测工程，提出布点方案、监测方法，通过对监测结果进行分析，指导相关施工。%It's necessary to monitor the deformation of deep foundation pit and existing pile for the safety of the pile and the foundation itself when the construction of the deep pit is close to the pile. This article, based on a certain deep foundation pit monitoring project which is near a pile foundation in the soft soil area,introduces the spots position arrangement and the working method,and guidances related construction by analyzing the monitor results.
