摘　　要：依托交通运输部建设科技项目,拟在水槽中进行波浪-结构物-软粘土地基相互作用的试验,由于软粘土地基的制备耗费大量的人力、物力和时间,大水槽的建模和试验成本远远大于小水槽,受项目工期、试验场地和试验费用的制约软粘土地基试验可重复性较差,由于缺乏在大水槽中进行类似试验的经验,故先在已有沙地基上进行预备试验。文章针对已在大比尺波浪水槽中开展的波浪-半圆型防波堤-沙地基相互作用的试验,从模型的设计与半圆型沉箱的制作、土压和孔压传感器的布置和钻孔埋设技术、半圆体沉箱的吊装技术以及试验过程中出现的问题和注意事项进行了说明,从而为大比尺波浪水槽中进行波浪-结构物-地基相互作用提供了一套合理可行的试验技术。According to the project belongs to the Ministry of Transport construction technology, tests aboutthe interaction between wave and structure and soft clay foundation will be carried out in the large scale wave flume.Because the soft clay foundation will be spent a lot of manpower, material and time, modeling and test cost is fargreater than the small scale water flume, so the test is poor repeatability. Due to the lack of a similar experience in alarge scale wave flume, the preliminary test was studied on the interaction between wave and semi-circular breakwater and sand foundation. From the physical model design and making of the semi-circular caisson, how to layout anddrill embedded sensors of soil and pore pressure, how to hoisting semi-circular caisson, test process and precautionswere described. It provides a reasonable and feasible technology about the test of wave-structure-foundation interaction in large scale wave flume.
