秦皇岛七里海潟湖水上钻探取样及勘察成果分析

Analysis on Drilling Sampling and Survey Results in Qinhuangdao Qilihai Lagoon

摘要:

秦皇岛七里海湿地生态修复工程主要通过退养还湿、清淤疏浚和岸线综合整治对七里海潟湖进行生态修复和景观提升。通过水上钻探取样技术，对七里海潟湖进行工程勘察，根据土层物理力学性质，分析该区域工程地质特征、液化分区情况和浅层土类别，对工程疏浚适宜性作出评价，为清淤疏浚和岸线整治提供有利依据。

Abstract:

In the ecological restoration project of Qinhuangdao Qilihai wetland, dampness returning, dredging and comprehensive management of shoreline are mainly used to improve the landscape. The engineering survey was carried out in Qilihai lagoon with the water drilling sampling technique, and according to the physical and mechanical properties of soil layer, the engineering geological characteristic, the liquefaction zoning and shallow soil category are analyzed, the suitability of dredging engineering is evaluated to provide the basis for dredging and shoreline management.
