摘要

The vibration load caused by the impact and explosion in construction exerts great influence on the surrounding earth. Therefore, the safe operating condition of gas pipeline is seriously influenced. For the first time, by use of smart microseismic monitoring system, such vibration caused by the impact and explosion is monitored and analyzed. First, it reveals the transmission law of vibrating wave forms. Second, the coupling calculating models of pipeline earth under the influence of vibration is built. Finally, the characteristics of exerted force and transformation of earth pipeline system are analyzed. According to these microseismic data obtained from the spot and numerical simulation method, the dynamic response of underground pipeline under compound vibration is studied; nonlinear mathematical model theory and method for coupling effects of earth and pipeline are bui the effects of vibration to pipeline are assessed; the feasible assessing method of safe operating condition of gas pipeline under vibration is explored and developed.
