文中利用理论分析的方法分析了大连某填海项目临时围堰施工对永久护岸地基变形的相互影响,并利用土力学理论分析了临时围堰施工可能造成的永久护岸变形特征,通过监测数据分析,找出了永久护岸变形异常的关键影响因素,并提出了减小临时围堰对永久护岸影响的几条措施和方法,达到了较好的处理效果。
The paper analyzes the mutual influence of the temporary cofferdam construction on the deformation of the permanent revetment foundation in a reclamation project in Dalian using theoretical analysis method and analyzes the deformation characteristics of the permanent revetment which can be caused by the construction of the temporary cofferdam by using the theory of soil mechanics. By analyzing the monitoring data, The key influencing factors of abnormal deformation of permanent revetment are found, and several measures and methods to reduce the influence of temporary cofferdam on permanent revetment are put forward, and a better treatment effect is achieved.
