摘要
引进了一种特殊的、易于计算操作的横观各向同性体———层状介质来描述岩体,并利用计算实例指出层状介质岩体的重要性和合理性.应用实例表明,对德国煤矿的深部开采,采用介质各向异性的强度为0 05～0 01较适宜.
Problems of application with isotropic rock model were discussed and a special transverse isotropic rock, the stratified rock, was introduced as a unified rock model for ground and strata movements calculations.Boundary element method(BEM) calculation examples with stratified rock were presented to show the satisfied application to the mining subsidence engineering. The applied examples show that anisotropic medium intension is proper in (0.05～)0.01 for deep mining in Germany.
