Study On Deep Foundation Pit Construction Monitoring In Metro Station Of Haizhu Square

With the development of high and ultrahigh construction, the utilizations of underground space become more and more important. Meanwhile, the number of projects with deep foundation has been rapidly increasing, design of retaining and protecting for foundation excavation and construction skill bcome the key technical problems. Because of deep foundation pit engineering is a complicated system that earth and lining structure are interactive, it is difficult to discover the state of destroy of lining structure and earth only by theory analysis and experience estimate. In further to carry on design and construction based on security, credibility, economic. Therefore that deep foundation pit implementation construction monitor, and design through the monitor information feedback analysis instruction and constructs has the extremely vital significance.This paper is based on the scientific research item of Guangzhou. A reliably conclusion is concluded through monitoring the water pressure, earth pressure, stress of reinforcing steel bar of wall, steel braces axial force, wall movement, settlement of earth surface in construction of zhuhai square station in Guangzhou metro line 2. And it can provide scientific proof and reasonable advice for security, economic and quickly construction of lining structure of deep foundation pit engineering of railway station.
