摘    要:针对国内外现有隧道围岩渗透力公式均未考虑衬砌渗透性影响的情况,依据无限含水层中井理论,把深埋隧道中隧道围岩、衬砌渗流概括为承压水向垂直井的运动,推导了轴对称条件下围岩、衬砌渗透力公式,并考虑了注浆圈对围岩、衬砌渗透力的影响,最后通过对比分析得出衬砌渗透性对围岩渗透力的影响很大,不能被忽略.当围岩渗透系数与衬砌渗透系数之比n增大时,围岩渗透力会不断降低,但当n>50时,n值对围岩渗透力影响不大.

关 键 词:隧道  围岩  衬砌  渗透力  解析解

Abstract:The seepage force,acting as a volume force upon the surrounding ground and the lining,was usually arbitrarily ignored but was taken into consideration in this paper.According to the theory of infinite aquifer wells,the seepage force formulas of surrounding ground and lining under the conditions of axial symmetry are deduced.The impact of the permeability of the lining on the surrounding ground seepage force can not be ignored by comparing the previous seepage force formulas with the deduced formulas.Meanwhi...
Keywords:tunnel  surrounding ground  lining  seepage force  analytical solution
