摘　　要：对含竖向排水体地基的固结理论进行了分析,研究了加载模式、竖向排水体间距及直径对软土路基固结的影响。结果表明,通过超载预压或者真空堆载联合预压可以较快地使软土固结,有利于减小工后沉降。The paper analyzes the consolidation theory of the soft soil foundation with vertical drainage body, researches the influence ot the load pattern, the distance among the vertical drainage bodies and the diameters on the consolidation of the soft soil foundation. It is showed by results that the surcharge preloading or the combined vacuum-surcharge preloading can consolidate the soft soil in a faster way and it is helpful to reduce the settlement after the construction.
