摘要(Abstract)：

分析了钻孔水泥浆液灌注过程中孔内水位变化以及管路虹吸现象对替浆量的影响;指出了以往替浆量计算方法的不足;根据水力学压力平衡理论修订建立了新的钻孔水泥浆灌注替浆量的计算公式。
The influences of the water level and siphonage on the water volume to replace the cement fluids in grouting hole are analysed. The shortcomings of previous formula for calculating the water volume are pointed out and according to the hydraulic principle of pressure balance a new formula for calculating the water volume to replace the cement fluids is established.
