[0043] Example 1
[0044] The section of a certain tunnel is circular, and the full-section excavation method is adopted, and the surrounding rock relaxation depth of the tunnel is within 2m. The stability of the tunnel is monitored by micro-seismic.
[0045] 1) The maximum monitoring range of the microseismic sensor in the rock mass of the monitored tunnel 4 is 180m, and the first group of four microseismic sensors in the first group of four microseismic sensors is arranged at the tunnel section about 90m behind the tunnel face 3, of which three are unidirectional microseismic sensors , Model is South Africa 1G14 microseismic sensor, natural frequency is 14Hz, response range is 7~2000Hz, one is three-way microseismic sensor, model is South Africa 3G14 microseismic sensor, its natural frequency is 14Hz, response range is 7~2000Hz, different types The sensors can work together, which is conducive to the location of the microseismic source. The microseismic sensors are installed i...
