摘要：

In order to study the physico-mechanical properties and slake durability of grouted completely weathered granite, triaxial shear test, permeability test and slake durability test were carried out with different grout filling ratios. The test results show that stress-strain curves transform from strain-hardening to strain-softening when the grout filling ratio increasing. With the increase of grout filling ratio, the cohesion and deformation modulus increase exponentially, and internal friction angle varies in parabolic form, while permeability coefficient decreases in the form of negative exponential. Based on these test results, regression equations of cohesion, internal friction angle, deformation modulus and permeability coefficient to grout filling ratio are established respectively. And the mechanism of grouting for reinforcement and water sealing has been discussed briefly. The research results have a guiding significance for the evaluation of grouting effect and determination on the grouting scheme and quantity. © 2016, Science Press. All right reserved.
