挤土桩施工对邻近防汛墙安全影响分析

Analysis on Impact of Displacement Pile Construction on Adjacent Flood Control Walls

摘要:

黄浦江和苏州河防汛墙是上海市防洪挡潮的主要工程措施，在防御风、暴、潮、洪四大灾害，确保城市的正常运行和人民生命财产安全等方面发挥了重要作用。随着上海市在黄浦江及苏州河沿线堤防周边开展的施工项目日益增多，桩基施工对邻近防汛墙结构安全的影响已发展成为需要重点关注的工程问题。采用有限元软件PLAXIS模拟挤土桩施工对邻近防汛墙的影响，定量分析防汛墙结构在桩基施工影响下的位移规律，确定了关键影响参数，供黄浦江及苏州河沿线堤防管理使用。

Abstract:

The flood control walls of Huangpu River and Suzhou River are the main engineering measures for flood control and tide prevention in Shanghai, which play an important role in ensuring the normal operation of the city and the safety of people's lives and properties in defending against the four major disasters of wind, storm, tide and flood. With the increasing number of construction projects carried out around the embankments along the Huangpu River and Suzhou River in Shanghai, the impact of pile foundation construction on the structural safety of the adjacent flood control wall has become an engineering problem needed for special attention. The finite element software PLAXIS is used to simulate the impact of displacement pile construction on the adjacent flood control walls, the displacement law of the flood control wall structure under the influence of pile foundation construction is quantitatively analyzed, and the key influence parameters are determined, which can be used for the embankment management along the Huangpu River and the Suzhou River.
