| 摘 要： | 大直径泥水盾构隧道下穿钱塘江防洪堤引起的大堤沉降的发展规律与通常情况下的盾构推进引起的地面沉降规律有着较大的不同,基于杭州市庆春路φ11.38 m盾构过江隧道工程实例,对隧道下穿江南防洪大堤的施工期间及其后续阶段大堤的沉降进行了长期的观测。文章根据实测沉降数据,主要从沉降发展的时间历程、施工各阶段沉降量所占比例和大堤的沉降槽特征等3个方面进行了分析研究。

| Abstract: | Characteristics of the settlement of the Qiantang River embankment caused by a large-diameter slurry shield tunnel under-crossing were quite different from those of surface settlements caused by routine shield tunneling.A large number of settlement observations were carried out during and after the Hangzhou Qingchun Road river-crossing tunnel passed under the southern embankment.Characteristics of the settlement of the southern embankment were analyzed in three aspects,including the history of past settleme... |
