Abstract

By means of borehole dilatometer method,the insitu measurement of elastic modulus was carried out in the F215 fracture zone of Three Georges Project inthedifferent stages.These results reflect changes of moduli at fracture zone rockmass before and after grouting,whick offer a better index to evaluate grouting effect.
