沿海盐碱地区绿地淡水层保护系统的设计

Design of Freshwater Layer Protection System for Green Area in Coastal Saline-alkaline Zone

在渤海湾某国际生态城内某校区的可持续水系统设计中,针对该滨海区域所存在的土壤盐碱化、地下咸水水位高等问题,提出了构建绿地淡水层保护系统的理念。介绍了绿地淡水层保护系统的构造、布置、部分工程细节及设计体会,着重分析了地下咸水水位控制及淡水层形成的原理,并通过地下水流模拟软件对淡水层的形成过程进行了模拟,为在沿海盐碱区域建设城市淡水系统提供技术参考。

In the design of the sustainable water system of a campus situated in an international eco-city along the Bohai Sea, the concept of freshwater layer protection system for green area was pro- posed to solve problems of soil salinization and alkalization and high underground salt-water level in this coastal zone. The construction, layout, part of the project details of this system and some design experi- ence were introduced, the principles of salt-water level control and the formation of the freshwater layer were analyzed, and the formation process of freshwater layer was simulated by groundwater modeling soft- ware, which provides technical reference for the construction of freshwater system in cities in coastal sa- line-alkaline zone.
