根据天津临港工业区二期围海T4、T5区真空预压工程的地质情况，阐述了二次加固直排法真空预压的施工过程，对一次加固及二次加固的效果进行对比分析。采用该方法在一次加固后有效地增强了地表土质的强度，保证了在二次加固时地表土层能够承受一定的上部荷载，不影响后续施工。

Based on the geological conditions of Tianjin Harbor Industrial Zone phase II reclamation zone T4 and zone T5 vac-uum preloading project, we introduced the construction process of secondary reinforcement inline vacuum preloading, analyzed and compared the effects of primary and secondary reinforcement. The strength of surface soil can be reinforced substantially by using this method after primary reinforcement, which can ensure that the surface soil can withstand some upper load in the sec-ondary reinforcement and do not affect subsequent construction.
