In order to avoid surrounding rock instability and guarantee the safe and efficient tunneling of deep-buried tunnel with high crustal stress, microseismic monitoring technology is used to monitor the surrounding rock fracture. And the different microseismic activities are used to characterize the potential risks of different high crustal stress hazards in tunnels. The construction procedures, time and methods can be reasonably selected based on the variation of high crustal stress hazard risk in tunnels reflected by dynamic evolution process of microseismic activity in monitoring area, and good effects have been achieved. Research results show that microseismic rule of surrounding rock helps to guide the construction process management of deep-buried tunnels and reduce the risks in construction process, which can ensure the safety of personnel and equipment and provide reference for other major deep-buried tunnels related to the Belt and Road Initiative in China.
