摘　　要：通过试验 ,跋山水库提出了替代常规水库大坝坝前先清淤后压重的施工方案——抛石挤淤压重 ,即直接进行抛石 ,把淤泥挤出压重体或挤入压重体块石之间 ,这样既节省投资 ,又缩短了工期 ,可供同类工程借鉴 ;文章对挤淤试验效果观测作了深入分析。Through experiments on construction of the Bashan Reservoir dam, a new construction method is put forward. Compared with conventional construction method, which is to clean up the bottom silt before placing weight blocks in place, the new method places weights directly by dumping riprap to squeeze off the bottom silt. This method saves both investment and construction time, and could find wide application in future projects. This paper presents an in depth analysis on the observation results of the experiment leading to this new method.
