中文摘要:抗浮锚杆是建筑工程中控制地下水浮力的重要技术。结合青岛星雨华府北区下沉广场基坑抗浮锚杆工程，基于现有抗浮锚杆设计理论进行了初步方案设计，并运用FLAC3D开展了数值模拟试验，分析了在结构荷载、地下水浮力和锚杆共同作用下基坑底板的受力和变形。在综合考虑受力和施工成本的情况下，得到了抗浮锚杆优化方案。

Design and optimization of the anti-floating anchor bolt for a foundation pit project in Qingdao
Abstract:The anti-floating anchor bolt is an important technique to control groundwater buoyancy in construction works. The anti-floating anchor bolt project for the underground square foundation pit in north Xingyuhuafu in Qingdao was taken as the research object. The preliminary design was carried out based on the existing anti-floating anchor design theory, and the numerical simulation test was carried out using FLAC3D. The stress and deformation of the foundation pit floor under the combined action of structural loads, underground water buoyancy and anchor bolts were analyzed. The optimization scheme for anti-floating anchor bolts was obtained through trade off of the loading conditions and construction cost.
