摘要
比较了围堰法、顶管法和定向钻法穿越河流的施工工艺及优缺点,探讨了天然气管道穿越永定河方案的比较及选择、对GB 50286—98《堤防工程设计规范》相关条文的理解,提出了为进一步提高安全性采取的技术措施。
The construction technology as well as advantages and disadvantages of cofferdam method, pipe jacking method and directional drilling method for crossing rivers are compared. The comparison and selection of natural gas pipeline crossing Yongding River schemes as well as the understanding on the relevant articles in Code for Design of Levee Project （ GB/ T 50286 - 98 ） are discussed. The technical measures for further improving safety are put forward.
