非开挖牵引管技术应用与有限元计算

Application of Trenchless Technology and the Finite Element Analysis of Pipe Structures

随着城市雨污分流建设的不断展开,非开挖牵引管技术在城市给排水管网工程中已经得到了越来越广泛的应用,文章简要介绍了非开挖牵引管的技术特点,阐述了牵引管主要的设计步骤及应注意的技术要点,阐述了管道强度和回拖力的计算方法;采用FLAC3D对牵引管进行了有限元分析。

With the development of the construction of the divided flow between the rain and the sewage,the technology of non-excavated tractive pipe has been more and more widely used in the projects of the urban water supply and drainage pipeline network.The paper introduced the technical features of the non-excavated tractive pipe,described the design procedure of the tractive pipe and the technical points that should be noticed,discussed the calculating methods of the pipeline strength and the pull strength.Finaly...
