裂隙岩体灌浆特性的研究

Study of Grouting Characteristic in Fractured Rock masses

裂隙是灌浆的主要对象，应用幂律液体摩阻力定律，推导出灌浆压力，浆液特性，裂隙开度及浆液扩散半径之间的关系式。在此式基础上，分析研究了浆液趋于牛顿浆液时裂隙中的压力分布。

Grouting technology has a very strong aoolicability and has been widely used in engineer.The grouting substance make solidfying grout pour into joints as well porosity and fracture etc.In rock masses,the rock masses form fresh structure masses with high strength and impermeability,thus the physical and mechanical properties of rock masses are improved.The main object of grouting is fracture,the relation expression among grouting pressure,grout charcteristic,fracture aperture and grout diffusion radius is derived by applying frictional resistance law of power law fluid in this paper.The interference ralition among the pressure distribution in fracture and each influence factor in grouting course are studied when grout fluid approach Newtonian fluid.
