【 摘 要 】

In this paper, the supporting scheme of a deep foundation pit project is designed, and the supporting structure system of complex horizontal support form and the ground wall are put forward. On this basis, the necessity of foundation pit construction monitoring is put forward, the contents, principles and basis of foundation pit monitoring are summarized, the purpose and function of foundation pit monitoring, the principles of designing monitoring system and the basic requirements of monitoring are clearly defined, the arrangement of displacement measuring points and data processing methods are emphatically studied, and the methods and methods of measuring point arrangement are given. The monitoring results of soil settlement around foundation pit, horizontal displacement of supporting structure and pit bottom uplift are analyzed and evaluated. It provides a reference for monitoring complex supporting forms of deep foundation pit.
