滨海盐碱地开发的竖向设计与排水问题探讨

由于地势低洼、排水不畅且易受海潮侵袭、地质条件复杂、土壤承载力低、土地盐碱化严重等原因，如何合理地确定场地竖向高程并有效组织雨污水排放成为滨海盐碱地区开发的最大难题。在进行滨海盐碱地区的规划设计时，应充分注意竖向设计与排水工程设计的结合，既保证场地回填的经济性，又保证雨污水能以最优的方式排放；充分利用地形、地貌条件组织排水，寻求经济有效的排水方案。

Discussion on the Vertical Design of Seaside Salina Area Development and Its Drainage Problem

Because of such factors as low -lying topography, unsmooth drainage, easy to be eroded by tides, complicated geo-conditlons, low bearing value of soil and serious soil salination, etc., It has become the biggest problem In development of seaside Sallna areas how to decide the vertical height of the site and how to drain out the sewage and rain water. Therefore attention should be paid to the combination of the vertical design with the design of the drainage projects in planning and design of seaside Salina areas in order to ensure both the economy of the backfill of the site and the drainage of the sewage and rainwater in an optimized way. Full use should be made of the topography for the drainage so as to find out the economic and effective means of drainage.
