【摘要】 针对先掘进盾构被后掘进盾构超越的特殊情况,以上海某轨道交通区间推进工程实例为背景,研究盾构超越施工技术在特殊条件下的应用.分析超越期间的地面沉降数据,明确超越施工对土体变形的影响,明确了对相邻盾构和隧道的影响程度,得到了地层的变形规律.更多还原

【Abstract】 The mutual influence between parallel shield tunneling during construction stage was introduced.The engineering background is from the project of Shanghai metro line,where the later launching shield transcends the earlier launching shield.The ground settlements during the transcending period was analyzed,the degree and scope of mutual influence are obtained.更多还原
