摘要
东武仕水库除险加固工程的重点是放缓上游坝坡 ,施工难点是处理坝前淤泥问题 .该淤泥层松软、饱水、强度低 .经方案论证 ,施工中采用砂井加压坡平台的处理方案 ,加速了地基的固结 ,提高了地基承载能力 .此施工方法达到了预期效果 。
The reinforcement project of Dong wushi Reservoir was carried out in 1997. The main point of reinforcement is to decrease the dam slope of the upper reaches. The difficulty is that process of construction must deal with the sludge layer in front of the dam . The sludge layer is very soft, saturated and it's strength is very low. Sand well and pressing slope platform is adopted in the process of constrution, which accelerates the rate of consolidation and heightens the carrying capacity of the foundation.
