大榭港区围海造陆工程软体排施工技术

Construction technique of soft mattress used in land reclamation at Daxie Port

针对大榭港区围堤工程施工特点,对排体适应性、布排结构及充灌砂量进行分析。改进了不同水位区排体和砂被的加筋处理技术,系统分析了深水位区、浅水位区及潮间带软体排铺排施工技术及改进措施。围堤水平位移和沉降监测表明,软体排整体性好,抗滑移强,土体沉降均匀,效果良好。

In consideration of the complicated construction condition of the land reclamation project, the feasibility of the soft mattress construction technique, the rational structure of the soft mattress, and the amount of sand filling were analyzed. The mattress and sand bag reinforcement technique for different water levels was modified, and the construction technique and modified measures for paving the soft mattress in deep water, shallow water, and intertide zones were systematically discussed. The horizontal displacement and settlement monitoring of the polder dike shows that the soft mattress is of good performance in structural integrity and anti-sliding effect, that the soil settlement is uniform during the construction, and that the effect of this construction technique is satisfactory.
