Design and Application of U-shape Groove in a Port Railway |
| |
| Abstract: | Combined with the special railway line project of a port, the application of U-shaped groove in long and large underground water road cutting has been introduced and the advantages and disadvantages of different U-shaped groove structures have been analyzed as well. Combined with the characteristics of the project, the down-dip trapezoidal section has been adopted for design, midas Civil has been adopted for structure design calculation. Meanwhile, key technical technologies such as anti floating design, waterproof design and support for temporary foundation pit excavation have been introduced in detail in this paper. |
