摘　　要：围岩注浆的均匀程度严重影响锚注技术的支护效果,基于现有锚注工艺的技术缺陷,结合现场工作经验,对均布注浆技术进行了深入研究。提出均布注浆的技术原理,形成卸压槽和震动卸压2种激隙卸压技术,完善均布注浆体系,同时分析注浆中主要参数选择条件和依据,形成不同围岩特征条件下的均布注浆方案,通过工程实践验证了均布注浆的效果。The degree of uniformity of rock grouting seriously affects the bolting supporting effect. Based on the defects of the existing technology of bolting technology and working experience in the field,the uniform grouting technology is studied. We propose theory of uniform grouting technology,and introduce two excitation gap pressure relief techniques of pressure relief groove and shock pressure relief,perfect uniform grouting system and conduct analysis of conditions and basis for the selection of the main parameters of grouting,form uniform grouting schemes under the different characteristics of surrounding rock. Through the project,practices certificated uniform grouting effect.
