摘要

本文首先采用爆破震动测试法对充填体内的地震波进行测试,然后根据数理统计原理运用最小二乘法进行方程回归拟合,获得测试区段充填体内破坏区和非破坏区的地震波衰减公式,进而通过解方程求算充填体内安全允许震速。然后采用声波测试法根据声波传播速度的变化分析爆破引起的充填体破坏状况验证所求得的充填体地震波衰减公式和安全允许震速的正确性。
At first this paper use the method of the blasting vibration to test the seismic wave on the filling body,then apply the principle of mathematical statistics and the least squares to fit of regression equation,and obtain the attenuation formula of the seismic wave at the failure zone and non-failure zone of the filling body,also by solving the equation to calculate the allowable safety vibration velocity of filling body.At last it use the sound wave test method with its features of that the change of the seisimic wave velocity can indicate the destroys state of the filling body,to validate the attenuation formula of the seismic wave at the failure zone and non-failure zone of the filling body.
