摘要随着我国沉管法修建隧道技术的发展，越来越多的水下隧道采用沉管法施工，而干坞是沉管隧道修建的重要因素之一。 | | 4. | This paper deals with seismic analysis of an immersed tunnel using the travelling wave method the objective of the analysis is to obtain the maximum stresses in the tunnel body and the relative displacements at the joints for design purpose in analysis ， the axial and transverse input waves are treated as two independent waves with different amplitudes and periods the method has been found to have the advantages of simplicity and clearness in physical concepts however ， reasonableness of the prediction by the method depends largely on the input data ， such as the wave amplitude ， the wave length ， the propergation speed of the travelling wave as well as the reaction coefficient of the ground thus ， determination of the input data is discussed in detail finally ， the method is applied to analysis of huangsha - fangcun immersed tunnel across the pearl river in guangzhou
将行波法应用到刚度较大、分段较多的水下沉管隧道的地震分析中，提出把轴向、横向两个输入波处理为两个独立的行波的方法行波法是否符合实际，与输入地震波的有关参数及地基系数选取有很大关系，作者对此进行了比较深入的讨论，使输入参数的选取简单、明确，便于对计算结果进行分析与判断最后应用此法对珠江水下隧道的工程实例进行了计算 | | 5. | This paper deals with seismic response of a tunnel - soil system immersed tunnel ， as an underground structure ， must be compatible with the deformation of the surrounding soil thus the simplified model for a tunnel - soil system is established through two steps at the first step ， an mdof system is developed for modeling the foundation soil to this end ， dynamic behavior of the foundation soil is analyzed a typical section of the foundation soil simplified as a single mass - spring system on the basis of some equivalent criteria those mass are linked longitudinally by elastic springs to form an mdof system at the second step ， the tunnel is treated as a beam on elastic foundation ; that is ， the tunnel is connected with the soil massed to form a tunnel - soil system this model has been applied to the seismic analysis of huangsha fangcun immersed tunnel across the pearl river in guangzhou design recommendation is proposed on the basis of this analysis
研究沉管隧道在地震条件下整体受力的分析方法分两步建立计算模型第一步通过分析场地地基土切片的动力特性，根据等效原则将其化为等效单质点体系，然后在纵向用等效弹簧连接而成为多质点体系的地基土计算模型；第二步将隧道看作弹性地基梁与上述多质点体系通过等效弹簧连结而得到土隧道体系的计算模型本文结合广州黄沙芳村珠江水下隧道工程实例建立了具体的计算模型并对多种不同的约束条件，进行了纵向与横向地震响应时程分析，为该隧道的抗震设计提供依据 | | 6. | Strip - shape underground structures such as the tunnels and tubes for various uses can be treated as a beam on elastic foundation under earthquake condition ， although there exists soil - structure interaction ， the foundation soil vibration is dominant in other words ， analysis of earthquake response of the soil is essential to this end ， simplified models ， ( i . e equivalent mass system models based on some equivalence criteria ) are proposed ， instead of a general 3 - d continuum model in this study ， equivalence criteria are proposed and the simplified models are compared the single - mass - string model is proved to be valid and therefore applied to the analysis of earthquake response of the pearl river immersed tunnel
条装地下结构如隧道、各种埋设管道等一般可看作弹性地基梁进行静力及动力分析在地震条件下，结构与土相互作用，但土的振动成为主要因素为分析土的地震响应需把基土这一三维连续体作简化处理，简化成为等效多质点模型本文着重探讨这种简化模型的建立方法，推导等效方程，通过几种简化体系的分析比较，论证单质点串体系的合理性，并将其应用到广州黄沙芳村珠江水下隧道工程的地震响应分析，为抗震设计提供依据 |
