漩门二期蓄谈围垦工程海堤高程防潮标准模型试验研究

Experimental Study on Altitude Tide Control Standard Model for Sea Embankment of Xuanmen Phase Ⅱ Xudan Reclamation Project

漩门二期蓄谈围垦工程海堤于2005年竣工,各段海堤均发生了不同程度的固结变形,按现行相关规范要求部分堤段高程已不满足规范设计要求,亟需对该段海堤进行相关防潮标准物理模型试验。本次选取工后沉降最大的断面,按设计水文要素对选取断面进行越浪量物理模型试验验证。试验结果表明,海堤固结沉降最大断面,波浪爬高和越浪量仍可满足规范,与规范计算值保持较强的一致性。

Sea embankments of Xuanmen Phase II Xudan Reclamation Project were completed in 2015.Since then,several sections have experienced consolidation and deformation of varying degrees,altitude of which failing to meet the current design standard requirements.It is urgent to conduct tide control standard physical model tests on these embankments.This study selected the section with maximum settlement and conducted wave overtopping physical model test according to hydrological design factors.Results showed that for the embankment section with maximum consolidation and settlement,the wave run - up and overtopping can still meet to the design specifcations,largely consistent with calculated values of specifcations.
