摘　　要：固结灌浆是指为了改变岩体裂隙发育或破碎岩体的物理力学性质而采取的一种工程处理措施。在山阳县磨沟水库工程中对坝基岩体进行的固结灌浆试验,使用压水试验、波速测试等方法对试验结果进行验证。结果表明:固结灌浆能改良或消除地基岩体中原有的浅层裂隙、结构面以及在开挖和爆破过程中引起的岩体卸荷裂隙等不良条件和缺陷,对提升地基稳定性和确保工程质量有较大的作用。Consolidation grouting is a kind of engineering treatment measure to change the development of rock fissure or the physical and mechanical properties of fractured rock mass.The consolidation grouting test of dam foundation rock mass in Mogou reservoir project of Shanyang County is verified by pressure water test and wave velocity test.The results show that consolidation grouting can ameliorate or eliminate the bad conditions and defects such as shallow cracks,structural plane and unloading cracks caused by excavation and blasting,and has a great effect on improving the stability of the foundation and ensuring the quality of the project.
