| Abstract: | The paper describes a construction plan of subgrade reinforcement by grouting the rock fissures within the reinforcement region,karst caves,grooves and water-eroded grooves till in the vicinity of the interface between earth and rock a "grout curtain" is formed so that underground channels are plugged and the erosion of to the upper bearing layer by groundwater is prevented. |
