Abstract For fresh hydraulic reclamation silt foundation，after improvement of no-horizontal-sand-drainage vacuum preloading technology，soil strength increases only a little，and the effective improved depth is very small. In view of this，soil engineering properties was analyzed and summarized of fresh hydraulic reclamation silt from different area，it is showed that high content of clay particles and strong hydrophilic minerals are one of major reasons why the drainage efficiency of vacuum consolidation drainage system is very low. Then，based on a project on shallow ultra-soft soil improvement in Gaolan seaport area in Zhuhai seaport，following the design principle of vacuum drainage system，a field experiment research was carried out of optimizing the vacuum drainage system. It was concluded that：(1) Based on transfer properties of vacuum degree inside the drainage system，it was better of scheme 3 (PVC filter tube-interspersed and fixed-common PVD) and scheme 4(horizontal integral PVD-matching connector-vertical integral PVD). (2) Based on transfer properties of vacuum degree among soil particles，scheme 4 was most advisable. Finally，some further suggestions were provided in future research.

Key words： soil mechanics fresh hydraulic reclamation silt drainage system of vacuum preloading technology design principle of vacuum drainage system optimizing the vacuum drainage system
