摘 要

在经济水平飞快提升的最近几十年间，各种高楼如春笋般拔地而起。建筑物基坑开工早已施挖的深度愈来愈大，范围也愈来愈广，高深度、广面积成为基坑的发展目标，同时周围的环境状况也趋于越来越繁杂，导致深基坑工程开工施挖的展开的难度愈来愈大。为了确保深度基坑开工施挖的安全进行，以及获取关于基坑支护方案的相关文献资料，必须全程监控该基坑工程的生产过程。本论文主要分成四个章节来阐述，前两章主要就该工程的各种相关情况进行简单介绍，第三章是以南京市九乡河闸站基坑监测项目为例，就基坑监测方案展开全面的分析，是全文的重点，第四章则简单阐述监测数据处理与安全保障措施的重要性。该监测项目包括支护结构顶端水平与沉降位移、深层水平位移、周边围墙沉降位移、周边油罐沉降位移监测。在观测过程当中，相关单位应及时向该项目设计部门、施工部门、监理部门等各部门报告所得到的相关数据，提高施工水平的信息化程度。

Jiuxiang penstock station foundation pit monitoring project

Foundation pit monitoring technology solutions

Abstract

In the recent decades of rapid improvement in the economic level, all kinds of tall buildings sprung up everywhere. The excavation of the foundation of the building has been excavated more and more depth, the scope is more and more wide, high depth, wide area has become the development goal of the foundation pit, while the surrounding environment also tends to more and more complicated, Pit engineering started digging the difficulty of expanding more and more. In order to ensure the safety of the excavation of the foundation pit and the relevant literature on the foundation pit support program, the production process of the foundation pit project must be monitored throughout. This paper is divided into four chapters to elaborate, the first two chapters mainly on the various aspects of the project related to a brief introduction, the third chapter is the Nanjing Jiuxianghe gate station pit monitoring project, for example, A comprehensive analysis is the focus of the paper, the fourth chapter is a brief description of the importance of monitoring data processing and security measures. The monitoring project includes the top level of the support structure and the settlement displacement, the deep horizontal displacement, the surrounding wall settlement displacement, the surrounding tank settlement displacement monitoring. In the observation process, the relevant units should promptly report to the project design department, construction department, supervision department and other departments to obtain the relevant data to improve the level of information construction level.

Key Words: horizontal displacement；deposition distance；deep horizontal displacement
