【Abstract】 A new method for calculating the aperture and roughness of fissure, and the effective radius of groundwater by using the response curve of a multistage pumping test is presented. Meanwhile, a new flow model of grout in two-dimensional fissure is established in this paper, which is used to analyze the influences of the roughness of fissure and the viscosity resistance of groundwater on the flow of grout. Some important conclusions are advanced.更多还原
