盾构隧道的反应位移法与抗震性能指标
|
摘要
详细介绍了用于盾构隧道横向、纵向抗震分析的反应位移法。通过总结我国现行规范,指出目前规范在盾构隧道抗震设计方面的不足之处;同时归纳总结了国外关于盾构隧道抗震性能的先进理论;结合国内实际情况,提出采用直径变化率和接缝张开量作为评价盾构隧道抗震性能的指标,并对这两个指标进行实际算例分析评价,得到典型盾构隧道在中等地震下的抗震性能表现,并将得出结果与现行规范对比,指出这两个指标评价盾构隧道抗震性能的合理性。
The response-displacement method for lateral and longitudinal seismic analyses of shield tunnels are introduced in detail.Based on actual conditions and the latest research,two indices,diameter variation rate and joint expand amount,are proposed to evaluate aseismic behavior of shield tunnels under certain ground motions.A seismic analysis is conducted for a certain shield tunnel using the response-displacement method,through which the aseismic behavior can be evaluated by the two indices mentioned above.A comparison of the results with current codes indicates the rationality of the two indices for evaluating aseismic behavior of shield tunnels.
