摘　　要：为了解裂面绿泥石化岩体与绿帘石石英错动面在灌浆前、后透水率、变(弹)模量、岩体纵波波速等物理力学指标的变化情况,为坝基加固处理措施的研究提供依据,在坝址区选择了3个试验区开展试验,并结合相关成果优化了固结灌浆的设计参数,提出合理的灌浆孔距、排距,灌浆方法、工艺,浆液配比、灌浆浆材及相应的灌浆压力等的评价与建议。In order to understand the changes of physical and mechanical indexes of Chloritized rock mass before and after grouting,such as water permeability,variable(elastic)modulus and longitudinal wave velocity of rock mass,and to provide basis for the research of reinforcement measures of dam foundation,three test zones are selected to carry out tests in dam site area.Combining with relevant achievements,the design parameters of consolidation grouting are optimized,and reasonable grouting hole spacing,row spacing,grouting method,process,grout proportion,grouting material and corresponding grouting pressure are put forward.
