以水泥类浆材为例,借鉴裂隙岩体渗透注浆的理论,分析了劈裂注浆时的压力衰减规律,得出土体中劈裂注浆的注浆压力、浆液的扩散半径以及裂缝宽度的相互影响关系。%According to the theory of permeation grouting on fractured rock,with the cement material for example,this paper has analyzed the law of pressure attenuation and the process of energy consumption during the whole fracture grouting.The result showed the relation among grouting pressure,diffusion radius and crack width.
