| Abstract: | 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. |
