Characters Analysis of the Retaining Structure of the Foundation Pit under Local Load

Abstract:

Taking one foundation pit engineering in Hangzhou for example, a numerical model of foundation pit under local load was established through the two-dimensional finite element software Plaxis. The influence on the displacements and bending moments of the retaining structure caused by construction process, the value and position of local load had been investigated. A simple discuss about local load' influence scope had been made. The results show that the displacements of row piles reach maximum after being excavated. As the values of local load increase or the distance between local load and foundation pit decrease, the status of the retaining structure becomes worse. Influence scope of load calculated in traditional method based on Rankine' theory may be rather small.
