- Abstract
The seepage monitoring effect of high - pressure jet grouting pile under different settlement heights is greatly different, and the greater the settlement height, the worse the monitoring accuracy. In order to ensure the seepage monitoring effect when the settlement height is high, the seepage monitoring method of high - pressure jet grouting pile in deep silt of sluice cofferdam is designed. Set the seepage equation, establish the seepage model of high-pressure jet grouting pile combined with the settlement height, and design the seepage monitoring algorithm. In the experiment, the permeability coefficients of the three monitoring methods under different settlement heights are compared. When the settlement height is more than 5m, the monitoring results of the other two comparison methods all exceed the standard values, which shows that this method can ensure the monitoring accuracy under a larger settlement height.
