The Experience and Discussion on Disposing Big Stone on the Construction of Anti-seepage Wall of Plastic Concrete in Qiannian Reservoir

During the construction of anti-seepage wall of plastic concrete in water conservancy engineering, big stones are usually encountered in the complex geology. The construction progress would be affected seriously, if some appropriate disposal methods are not found. Under some appropriate conditions, the method of under-water explosion is good to solve this problem. The article introduces the geological condition of anti-seepage wall in Qiannian Reservoir, the process to dispose big stone, and summarizes the disposing experience.
