摘要
Abstract
In order to ensure the operationof existing traffic safety structures during the short distance construction of shield tunnel this paper takes the No.48 and 49 of Fuzhou Bridge Pier Engineering,which nearby passes through shield section on Wanqingsha of Pearl River Estuary tunnel as an example,establishes a detailed nu-merical simulation model considering multiple factors such as grouting behind the wall and formation loss rate.The safety assessment and analysis were carried out on the interaction between pile piles of shield side cross-ing Fuzhou Bridge after formation reinforcement.The results show that the strengthening measures are reason-able and effective,which can control the deformation of bridge pile and soil around the pile.关键词
