摘　　要：吹砂填海区一般具有地势平坦、地质条件差、水土腐蚀性强等特点,若经真空预压-排水板地基处理,地下还会遗留塑料排水板,对片区排水管建设造成不利影响。以温州滨海核心区吹砂填海区市政排水设计为例,通过一系列优化措施形成一套因地制宜、经济合理的排水设计方案。Sand blowing reclamation area generally has the characteristics of flat terrain, poor geological conditions and strong erosion of soil and water. If vacuum preloading-drainage board technology is used for foundation treatment, plastic drainage board will still be left underground, which will cause adverse effects on drainage pipe construction in the area. Taking the municipal drainage design of sand-blowing reclamation area in coastal core area of Wenzhou as an example, a set of economic and reasonable drainage design scheme is formed according to local conditions through a series of optimization measures, which is expected to provide reference for similar engineering design.
