摘要

摘要: 引起越江隧道纵向变形的因素众多，河床冲淤便是其中之一，尤其是对于钱塘江这种河床高层年季变化较大的大冲大淤型河床。以钱江隧道为工程背景，基于Winkler假定和弹性地基梁提出了河床冲淤对于隧道纵向的分析方法，并与模型试验结果进行对比，论证了该方法的合理性。并以此方法探讨了钱塘江越江隧道在最不利工况下的受力变形特征，为工程实际提供一定的理论依据。

Abstract: Numerous factors may affect the longitudinal deformation of river-crossing tunnels, and one of them is the riverbed scour and siltation. Qianjiang River has great annual and seasonal changes. For the case of Qianjiang Tunnel, on the basis of the Winkler model and the elastic foundation beam, a method for analyzing the influence of the riverbed scour and siltation on the river-crossing tunnel is proposed. By comparisons with the results from the model tests, the rationality of the proposed method is proved. The further discussion on the deformation characteristics of Qianjiang Tunnel is carried out under the most unfavorable conditions, and it may provide theoretical basis for the engineering practice.
