摘要 通过新型桶式基础防波堤的原型观测试验,实现对结构所承受的土压力、孔隙水压力和倾斜度等的观测。试验分析了基础各部位的应力最大值以及气压纠偏对总应力的影响,表明新型桶式基础防波堤在负压下沉中具有良好的稳定性,对大型离岸深水构筑物的原位观测有一定的指导意义。 Based on the in-situ test of bucket-based breakwater, we realize the measurements of soil pressure, pore water pressure and gradient on the structure. The test analyzes the maximal stress on each part of the structure. The result shows the new bucket-based breakwater is stable when driven by negative pressure and it makes sense for in-situ test of large-scale offshore deep-water structure.
