摘要
为了研究注浆体的力学特性,利用RMT-150B岩石力学试验机,对其进行了三轴压缩试验。试验结果表明:不同矿物颗粒粒径的注浆体的强度不同,随着围压的增加,粒径对注浆体的强度影响变小。利用RLW-500岩石流变试验机对注浆体试件进行了三轴压缩分级加载蠕变试验,对注浆体的流变特性进行了初探。
In order to study the mechanical properties of grouting material,triaxial compression tests were conducted by using rock mechanics test equipment RMT- 150 B. The results indicated that grouting material of different particle sizes differ in intensity and with the increase of confining pressure,the influence of particle size on intensity is smaller. Triaxial compression multi- stage loading creep tests on grouting material samples were conducted and rheological behaviors of grouting material were studied by using rock rheological test equipment RLW- 500.
