Analysis of the causes of the seawall sinking slip in Yugang marina project of Kanmen Center

本文主要利用原位监测资料,及相关的施工记录,对坎门中心渔港码头工程的海堤沉滑事故进行了原因分析,结果表明,本次海堤沉滑事故主要与地基排水不畅,有效应力增长缓慢,海堤堤顶与涂面高差过大,未按设计要求进行加荷有关,并提出了增加内侧镇压层的加固方案。

This paper analyses the causes of the seawall sinking slip accident happened in Yugang marina proiect of Kanmen Center, combining with in--situ monitoring data, and related construction records; The result showed that the incidents of the sea wall is caused by the following reasons： first is the foundation drainage blocked and make effective stress growth slowly, second is large difference between the crest of seawall dike and the painted surface, and final is the loading did not satisfy the design requirements. According to the analysis above, the scheme of to increase the suppression of the medial layer of reinforcement is put forward.
