【 摘 要 】
Gunung Anyar is one of the areas in East Surabaya which has quite a high indication of the spread of soil clay with The combined Cv is 0.0008 - 0.000125 cm 2/s, which indicates long a consolidation time. The appropriate soil improvement method to speed up the consolidation time is to use a combination of preloading and prefabricated vertical drain. Simple statistical analysis was performed to obtain prefabricated vertical drain's thickness and length in general is 3.33 mm and 100 mm. The analysis consists of the effect PVD installation distance which is 1 m, 1.5 m and 2 m of triangular and rectangular patterns and variations thickness of soft soil clay are 10 m, 15 m, and 20 m. At the same installation distance with different thickness of soft soil layer, the changes of degreethe of consolidation was only
