摘　　要：采用钻孔弹性模量计对三峡F2 15断层带灌浆试验不同时期的岩体弹性模量进行了测试 ,测试值反映了灌浆前后断层带岩体弹性模量值的变化 。By means of borehole dilatometer, the in-situ measurement of elastic modulus was carried out in the F215 fracture zone of Three Georges Project in the different stages. These results reflect changes of moduli at fracture zone rock mass before and after grouting, which offer a better index to evaluate grouting effect.
