摘要
随着城市地下空间的不断开发,盾构技术在地铁线路建设中的应用越来越广泛。特别是在城市核心区域,由于既有地铁线路的密集布局,盾构长距离下穿既有地铁线路成为新的技术难题。本研究首先分析了盾构下穿既有地铁线路的技术难点和风险,随后介绍了针对这些难点的技术研究和应对措施,并通过实际工程案例验证了技术方案的可行性和有效性。旨在为类似工程提供技术参考和经验借鉴。
With the continuous development of urban underground space,the application of shield tunneling technology in subway line construction is becoming increasingly widespread.Especially in the core areas of cities,due to the dense layout of existing subway lines,the long-distance penetration of shield tunneling through existing subway lines has become a new technical challenge.This article first analyzes the technical difficulties and risks of shield tunneling through existing subway lines,and then introduces the technical research and countermeasures for these difficulties.The feasibility and effectiveness of the technical solution are verified through practical engineering cases.This article aims to provide technical references and experience for similar projects.
