| 摘 要： | 为避免盾构隧道抗震设计动力时程分析的复杂性和减小计算工作量,对圆形隧道抗震设计的3种近似解析方法进行了比较.第1种是基于复变函数的近似解析方法,并用成层地层振动方程获得的地层剪切力进行了改进;第2种是基于贝塞尔函数的近似解析方法;第3种是基于弹性力学的近似解析方法.分别采用上述3种近似解析方法和反应位移法对某隧道进行了抗震分析.结果表明:前2种近似解析方法的计算结果较接近,规律大致相同,因此可用二者计算结果的最不利组合进行抗震分析;第3种近似解析方法较为粗略,只可用于圆形隧道抗震设计的前期估算.

| Abstract: | In order to cut down the complexity and workload of seismic analyses,three approximate analytical methods for seismic design of circular tunnels were discussed.The first one is based on the function of complex variable and improved by using shear stresses in strata gained by the vibration equation for stratification strata,the second one is founded on the Bessel function,and the third method is grounded on the theory of elasticity mechanics.Seismic analyses of a circular tunnel were carried out respectively... |
