摘　　要：介绍了天津南港工业区一期东二区工程的特点,对传统真空预压工艺中的水平向排水系统进行改良并对改良后的施工效果、效率以及成本进行探讨分析。采用该改良工艺的实际加固效果不低于传统真空预压加固效果,且更为节省成本,有较大的应用推广价值。This paper introduces the characteristics of the second area in the east of the first phase of Nangang industrial zone in Tianjin, the improvement of the horizontal drainage system for the traditional vacuum preloading technology, and the analyses of the results, efficiency and cost of the vacuum preloading technology after the improvment of the horizontal drainage system. It is concluded that the effect of improvement with the improved technology is no less than the traditional vacuum preloading consolidation effect, but the improved system saves more and have larger promotion value.
