摘要
针对软弱富水地层地铁盾构到达施工中容易出现安全事故的现状,介绍了水中进洞施工原理,从挡墙制作、水土回填、盾构到达掘进方面分析了水中进洞施工技术,指出水中进洞施工技术具有推广应用的价值。
In light of the safety accidents of arriving into shaft on soft clay region, the paper introduces the principle of arriving into shaft under water, analyzed the construction technology of arriving into shaft under water from retaining wall manufacture, soil backfill, shield tunneling in tunnel, and finally points out its application in subway shield tunnel engineering.
