深基坑支护是隧道施工中主要的施工技术,在各地不同的地质条件下取得了较多的成功经验,甚至一些工序施工已达到了较高的技术水平,但仍因特殊的环境条件,仍需进一步研究或提高。通过西北地区主要城市隧道深基坑支护施工技术的选择应用,总结了一套较完整的铁路临边深基坑工程支护技术,经济、安全可靠,以便于推广应用。
Deep foundation pit support is the main construction technology in tunnel construction. It has gained more successful experience under different geological conditions in different places, and even some construction has reached a higher technical level. However, due to special environmental conditions, Still need further study or improvement. Through the selection and application of the deep foundation pit supporting technology in the major urban tunnels in Northwest China, a complete set of supporting technology for the deep foundation pit of the railway is summarized, which is economical, safe and reliable, so that it can be popularized and applied.
