摘　　要：以山西省汾河水库新增建的泄洪隧洞为例，研究了在淤泥下岩塞爆破的试验模拟方法、试验技术以及有关的试验成果；并根据模型试验成果，制订了爆破现场实施操作方案．1995年4月25日在汾河水库现场对新建隧洞进水口进行了岩塞爆破，爆破库水位为1112．50m，采用平板门和弧形门全开，用关闭平板门控制的闸门操作方案，启爆后平板门开始关闭时间不得早于10min．经现场实际爆破验证了试验成果的正确性．这次在淤泥下岩塞爆破的成功，在国内外尚属首例．Taking the newly constructed Spillway tunnel of a large reservoir in Shanxiprovince as an example, this paper has studied the experimental simulation method and its techniques for the rock plug blasting in mud. On the basis of the model experimental results, an operation scheme for on--site rock plug blasting is worked out. The real rock plug blasting in the tunnel site has tested the correctness of the experimental results. It is the first time nationally and internationally that rock plug blasting in mud has been successfully made.
