Study On Deep Metro Foundation Pit Construction Monitoring And Deformation Of Nearby Road

With the development of high construction and the utilizations of underground space, the number of deep foundation pit in high construction, metro, underground carport and underground market has been rapidly increasing. Therefore that construction, enclosing structure and monitoring of deep foundation became more and more important.Most of the earth in SHENYANG is grit and the ground water very abundance. The paper is base on the deep foundation of SHENYANG first line QIGONG metro station, monitoring the pile movement, steel braces axial force and settlement of earth surface in construction of the metro deep foundation. After study the monitoring data, a reliably conclusion is concluded that the change of steel brace axial force; speed, maximum of pile movement are normal and the deep foundation is safe. Numerical simulation about the whole deep foundation and nearby road by ANSYS, simulate the destroy of road while different pile movement happened, a reliably conclusion is conclude that the road has destroyed while the pile movement is six centimeter. It can provide scientific proof and reasonable advice for security, economic and quickly construction of lining structure of deep foundation engineering of railway station, the experience and advice can used for other analogous deep foundation.
