英文摘要：

In order to investigate waterproof controlling theory and technology of soft rock roadway,a device was designed to measure the relation between permeability coefficient and void ratio for mud class swelling rock in the states of initial pressure, constant volume under loading, and grouting with initial pressure. The seepage process for swelling soft rock in the three states was investigated and three types of relation between permeability coefficient and void ratio were reached. According to water inrush mechanism of roadway and working principle of effective stress, the mechamism for effective stress increase and pore water pressure decrease during grouting process was analyzed, which can provide a theoretical basis and experimental parameters for grouting strengthening waterproof of soft rock roadway. Industrial test and measured results show that, surrounding rock strengthening controlling and grouting strengthening technology gave significant effect for the waterproof of swelling soft rock. The technology is easy to construct and promising in application.
