摘要

研究目的:武汉长江隧道周边工程环境复杂,其中盾构下穿既有武九铁路是该工程的难点之一。为比较准确地分析盾构下穿武九铁路的沉降影响,本文分别采用经典的Peck法和有限元法计算了盾构推进对武九铁路的沉降影响,介绍了施工中所采取的保护措施和现场监测情况,为同类工程积累了经验。
研究结论:施工过程中的现场沉降监测结果大于计算结果,但未影响铁路的安全运行。由于列车运行的影响,下穿铁路引起的地表沉降槽宽度和深度均大于邻近的和平大道。

Abstract

Research purposes: The surrounding engineering environment of Wuhan Yangtze River Tunnel is complicated, and the shield under-passing the existingWuhan -Jiujiang Railway is one of the difficult points in the project. For accurate analysis of the settlement of the railway caused by the shield underpass, this paper calculates the influence of the shield driving on the settlement of Wuhan -Jiujiang Railway with the classical Peck Method and finite elementmethod respectively and introduces the protective measures taken in the construction and the onsite monitoring situation to provide the reference to the similar projects.
Research conclusions:The on site monitoring resultof the settlement is greater than the calculation resul,t butitdoesnot affect the traffic safety of the railway. Due to the impact of train operation, the trough width and depth of surface settlementcaused by the under-passing railway are both greater than those of the adjacentPeace Road.
