| 摘 要： | 首次将一种基于集中质量法的力学模型用于分析计算软体排沉排受力和构型。该力学模型解决了不均匀质量、可拉伸软体排排体的构型和拉力分布的分析计算问题,并能考虑实际河流环境中水流的作用力。实例计算结果的讨论以及与悬链线理论解进行对比可知基于集中质量法的力学模型更适用于实际河流环境下的软体排排体的受力分析。

| Abstract: | A Lumped-Mass method is presented for the first time to analyze the tension force subjected by flexible mattress and its configuration.The method takes account of the elastic extension,non-uniform mass distribution of the mattress and the acting force due to flowing water.Comparing the calculation result by this method and that based on the catenary theory,we know that the Lumped-Mass method is more applicable for analyzing the flexible mattress in real fluvial environment than the commonly used catenary theory. |
