| Abstract: | The overburden of the upstream cofferdam foundation of XiaBandi reservoir dam is 150m deep, with 2 layers of soft soil at its upper part and a strong permeable layer at its lower part. The cofferdam construction period is very short, and the seepage control and stability design of cofferdam is faced with great challenge and risk. A great deal of calculation analysis and option justification has been done in the process of cofferdam design. Strengthened control and monitoring in construction has ensured smoo... |
