| Abstract: | 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. |
