深基坑工程对紧邻的黄浦江防汛墙的影响分析

Analysis of Impact of Deep Foundation Works on Adjacent Flood Control Wall of Huangpu River

以某紧邻黄浦江防汛墙的深基坑工程为例,阐述了深基坑工程全过程施工对防汛墙的不利因素。通过有限单元法研究分析了邻近荷载、深基坑开挖阶段防汛墙的位移情况,为围护设计方案和基坑开挖方案提供理论依据。通过理论研究与实践,制定了拉、压、限、顶等具有针对性的防汛墙保护措施,确保了施工安全,并为类似工程积累的经验。

Taking a deep foundation pit project adjacent to the flood control wall of Huangpu River as an example,the unfavorable factors of the construction of the whole process of deep foundation pit project on the flood control wall are described.The displacement of the flood control wall during the excavation stage of the deep foundation pit is analyzed by the finite element method to provide a theoretical basis for the design of the retaining support and the excavation plan of the foundation pit.Through theoretical research and practice,targeted flood protection wall protection measures such as pulling,pressing,limiting and topping are developed to ensure construction safety and accumulate experience for similarprojects.
