Study on the Technique of Seawater Intrusion Prevention Through Water Supply by Groundwater Reservoirs in Coastal Plain

本项研究重点对地下水库建库研究成果作了介绍，其成果有，地下水库水资源量计算应用参数成果、地下坝设计孔距计算及板墙厚度计算应用公式成果、地下水库不同回灌工程补给强度成果（建闸蓄水回灌）、地下坝物理力学指标成果、地下建库预期目标及完成情况，并结合建库设计需要，首次提出了建库设计水源计算以及高喷建坝设计计算应用的变参方程，解决了建库供水水源计算以及高喷建坝设计计算的难题，为滨海平原缺水地区供水开源兴建地下水库提供了科学依据及建库方法．

In this paper, part of the study result is presented of seawater intrusion preventionthrough water supply by underground reservoirs which are built by high pressure jet grouting inthe coastal loose sedimentary deposit areas in China. Combining with the dam design, it is thefirst time to raise parameter equation for water resources calculation of underground reservoir design and hole distance calculation formula of different rock strata and reservoir depth for dam design calculation. It solves the difficult problem of dam design by high pressure jet grouting andwater resources calculation, provides scientific basis and dam building methods for supplying water and building underground reservoirs in the coastal water-deficient areas.
