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，当穿越某一新建海堤时，其最大沉降量达５８５ｍｍ，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。
Ground settlement may accompany pipejacking for complicated reasons, such as ground disturbance and ground loss. Description is given of the pipe jacking through a newly built sea embankment, causing great differential settlement, with the maximum up to 585mm. Based on site measurement, analysis is made of the ground loss and surface settlement of the embankment, and the reconsolidation settlement of the disturbed soil.
