摘    要:用弹性动力学波函数法,推导出由钢板衬砌,混凝土填充和围岩组成的地下圆形 隧洞在P波作用下的动应力和位移表达式;以及P波幅值表达式。通过白山电站 2#引水管道分别对围岩松动与不松动情况以及有、无钢板衬砌之两种情况进行电算。 计算结果表明,位于震中附近的隧洞衬砌,在7级地震作用下要考虑钢板衬砌的抗 震防护.

关 键 词:波函数  隧洞衬砌  动应力

Abstract:The dynamic stresses and displacements of circular tunnel which consists of steel plate liner and concrete filling in rock medium acted by P waves are determined by elastic dynamic methods, and the formulas of the amplitude of P waves arc derived. The tunnel of 2# intake conduit of the Baishan Hydro -Power Station is calculated by computer for the case of firm or loose sur-rounding rock with or without steel plate liner. The results show that, even if the tunnel is acted by earthquake with a magnitude of M=7, the earthquake resistance in the pressure conduit of the tunnel-type should be considered. If the displacements of the ground surface is known, then dynamic stre- sses of underground structures would be calculated.
Keywords:wave functions  tunnel lining  dynamic stress
