Numerical Simulation of Curtain Grouting in Deep Borehole and the Application

Abstract:

Influenced by the facts of verticality of the borehole, grouting pressure and diffusion radius, technical difficulty is increased in grouting, which directly influences the curtain shape and seepage control effect. Based on the numerical simulation method of Universal Distinct Element Code, pressure distribution and grout diffusion in deep hole are simulated, which can give reference and guidance to the design and construction for curtain grouting.
