禹城通裕阳光豪庭基坑工程施工工艺对周边建筑物的影响分析

Influence of the foundation pit construction process in Yucheng on surrounding buildings

山东禹城通裕阳光豪庭基坑支护工程中因设计及施工工艺对周边建筑物影响较大,针对地层及周边环境对施工工艺及施工顺序进行优化,采用旋喷扩大头锚索,改变支护桩钻进及下笼方法,局部采用SMW工法,施工中加强监测,以上措施确保了工程顺利进行,施工经验可供以后类似工程参考。

In view of the grave influence on surrounding buildings due to the design and construction process of the Tongyu Yangguang Haoting foundation pit support project, some measures were taken to ensure the smooth progress of the project, such as optimization of the construction process and construction sequence according to the stratum and surrounding environment, adoption of jet grout expanded anchor cables, change of the support pile drilling and rebar cage lowering methods, local adoption of the SMW method, intensification of monitoring during construction. The construction experience can be used as a reference for similar projects in the future.
