Analysis and Research on Early Closure of Settlement Post-cast Strip for a Type II Residential Land Project

A Class II residential land project in Daxing District, Beijing is surrounded by multiple high-rise residential buildings and an underground parking garage. To eliminate the adverse effects of differential settlement, multiple post-cast strips were installed. The existence of post-cast strips seriously restricts the project schedule. Therefore, based on the geological conditions of the site, the foundation scheme, and the distribution of loads on the upper structure, PLAXIS3D was used for settlement analysis, and the early closure of settlement post-cast strips was feasibility according to practical engineering experience. The project implemented an early closure of the post-cast strips, thereby accomplishing the intended objectives.
