| 摘 要： | 顶管在顶进过程中 ,产生地层扰动和地层损失 ,从而导致地面沉降。地面沉降的原因是错综复杂的 ,文中所述顶管工程 ,当穿越某一新建海提时 ,其最大沉降量达 5 85 mm,并伴随较大的差异沉降。本文以该工程的实测沉降为依据 ,分析了顶管施工过程中所产生的地层损失和堤面沉降 ,分析了受扰动土体的再固结沉降

| Abstract: | There was ground settlement caused by ground disturbance and ground loss during pipe jacking construction. The cause of ground settlement is complex. In this thesis a case was described that the maximum settlement induced by pipe jacking construction through embankment was 585mm with diverse settlement. Based on the practical settlement in the project, in this paper the ground loss and surface settlement during the pipe jacking as well as the re consolidation settlement of the disturbed soil was analyzed. |
