关键层下软弱岩层厚度对关键层影响数值模拟研究
Numerical Simulation Study on The Effect of Thickness of The Soft Rock under Key Stratum to the Key Stratum
关键层是控制岩层移动与地表变形的主要因素，本文通过数值模拟结合压力拱理论，针对关键层下部软弱岩层厚度对关键层的影响进行了研究，结果表明：关键层下部软弱岩层对关键层的稳定有影响，说明在实践中必须考虑关键层在现实中的相对位置关系。
he key stratum is the main factor to control the movement of rock and the deformation of the earth’s surface,the paper study on the the effect of the thickness of the soft rock under key stratum to the key stratum by numerical simulation and the theory of the pressure arch.The results showed that:the soft rock which is under the key stratum will affect the stabilization of the key stratum,so,we must consider the relative position of the key stratum in practice.
