随着城市轨道交通的发展,选择一种合理的轨道施工技术非常重要。而盾构施工技术作为其中一项重要的技术之一,虽然其投资大、造价高,但其快速、安全、减少地面沉降等也是其他技术无法比拟的。本文就作者的工作经验,论述了我国盾构技术的发展及其现今存在的一些问题。供同行参考。 With the development of urban rail transit, it is very important to choose a reasonable orbital construction technology. As one of the most important technologies, shield construction is one of the most important technologies. Although its investment is huge and its cost is high, its technology is quick and safe, and its ground subsidence is also reduced by other technologies. In this paper, the author’s work experience, discusses the development of shield technology in our country and some of its existing problems. For peer reference.
