摘要：

在水利工程和海岸工程中,土工织物充填管状袋技术已得到了广泛的应用,然而,对其的设计还存在着许多必须解决的问题。文中编制了土工织物充填管状袋的设计流程,在分析比较国内已有相关规范的基础上,引入了GRI的土工织物材料和施工规范,研究绘制了土工织物充填管状袋充填时的设计图谱,并对土工织物强度准则作了相关介绍,进行了具体工程设计实例的计算。结果表明:提供的设计方法可较好地进行形状和强度计算。最后,提出了设计研究中需进一步研究的问题。

The technology of geotextile tubes has been widely used in hydraulic and coastal engineering.However, there are still many issues in the designs, which must be solved. The authors have worked out a design process for the geotextile tubes in this paper. On the basis of their analyses and comparison of the available domestic specifications, they introduced the Geosynthetic Research Institute's specifications for geotextile materials and installation of geotextile tubes and produced the design diagrams for the geotextile tubes in the process of filling. Illustrations were also made on the criteria of strength of the geotextile tubes. An engineering design example is presented, showing that the design method presented in this paper can be well used to calculate the shape and strength of the geotextile tubes. Finally, issues to be further studied and researched in engineering designs are proposed.
