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.
