摘 要
21世纪无论是经济水平,还是科学技术,都在高速发展,就建筑基坑而言,大型基坑正在逐步取代小型基坑,基坑越大、越深,危险程度就越高。对此我们更需要重视基坑工程的施工安全。对于大型基坑工程,为保证基坑及其周围建筑物的安全,建设单位须委托有资质的监测单位对基坑进行安全监测。在此,本人就基坑安全监测相关方面知识进行论述,本毕业设计内容总共有四章,第一章为基坑变形监测的概述,第二章为基坑监测的基本知识,第三章为本次毕业设计的重点,即以江苏省财政厅地下停车库基坑为例,编制一份详细合理的监测技术设计方案,并结合相关数据进行监测分析。就目前而言,基坑监测领域还存在着许多不足,由于监测技术,监测理论不够全面,但基坑的规模却越来越大,同时地质条件复杂多变,这就使得基坑监测工作变得异常的重要同时极具挑战性。本文最后章节即是对基坑监测过程中存在的问题和展望进行简单说明。

ABSTRACT
The rapid development of science and technology, the foundation pit engineering are constantly upgrading from the previous simple little foundation to the present complex deep foundation pit, we should pay more attention to the safety of construction, excavation for large foundation pit engineering, therefore, in order to ensure the foundation pit and the safety of the surrounding buildings, the construction unit shall entrust a monitoring unit of qualification safety monitoring of foundation pit. Here, I have the relevant knowledge of the foundation pit monitoring are discussed, the design content of a total of four chapters, the first chapter is an overview of the foundation pit deformation monitoring, the second chapter is the basic knowledge of foundation pit monitoring, the third chapter is the focus of this graduation design, the finance department of Jiangsu Province under the parking pit cucchi for example, preparation a detailed and reasonable design scheme of monitoring technology, monitoring and analysis with related data. At present, the foundation pit monitoring field still has many deficiencies, the monitoring technology, monitoring theory is not comprehensive enough, but the pit scale is growing, and complex geological conditions, which makes the foundation pit monitoring work has become an important and challenging anomaly. The last chapter of this paper is a brief description of the existing problems and prospects in the monitoring process of foundation pit.
Key words: underground parking; deep foundation pit; monitoring scheme; monitoring analysis
