连云港西大堤合龙口施工

简要介绍连云港西大堤合龙口的施工概况。为选择合理的合龙施工方案，首先必须估算出龙口内的真实流速，并结合工程实际，采用了合龙口“先减宽抛填断面截流合拢，再爆破补抛加宽形成全断面”的施工方案。实践证明，该方案不仅能降低成本。

The general situations of construction of the the west dyke closure mouth of Lianyungang Port is briefly introduced In order to select a rational construction scheme, the real flow velocity inside the closure shall be estimated first Then the scheme “intercepting the closure through filling first and forming the whole cross-section by supplementary filling through explosion later”is adopted Practice has proved that it can not only cut down cost, but also meet the requirement of construction period by adopting this construction scheme
