［摘要］某下沉式广场根据地勘部门口头提出的抗浮水位进行了抗浮设计，由于地下水位的波动性及抗浮桩设计施工中的不足，导致下沉广场出现上浮，结构开裂，并将给相邻的主体建筑带来不利影响。在现场施工条件有限的情况下，设计方面选用了钻孔锚杆桩作为抗浮事故处理措施，经过工艺试验及承载力试验，达到了设计要求，锚杆实施后效果明显，保证了工程安全和使用功能。

Abstract:One subsiding square has been designed according to the data of underground water level orally given by a geological prospecting section. But owing to the fluctuation of the water level and the insufficient bearing capacity of the buoyantresistancepiles in designing and real construction, the square came to float up and some structural leaks occurred, which also might ruin the safety of its neighbor buildings. Under limited site conditions, related designers selected installing anchor piles as a treatment with the accident. Now through technical experiments and bearing capacity experiments, it has proved that the treatment reached the designing requirement effectively. The application of the anchor pile ensures the safety and the function of the construction.
Keywords:buoyant resistance design; anchor pile; pulling resistance pile; underground water level of buoyant resistance design
