| 摘 要： | 针对某港区新近吹填淤泥形成的超软土地基,在施工机具和设备均无法进入的情况下,先采用直排式真空预压法在场地表面形成具有一定承载力的硬层,再按常规真空预压法进行二次处理,采用这种新方法处理后的软土地基承载力可提高到80 kPa,地基加固处理的效果显著.

| Abstract: | Since the ultra-soft foundation is formed by fresh dredger filled mud within some port area,no construction equipments could enter or be used in the area.In that case,the following foundation treatment method is adopted in the project,i.e.straight-line vacuum preloading is carried out firstly so as to form a hard layer whose bearing capacity is acceptable,normal vacuum preloading is applied for the secondary foundation reinforcement.As the new method is used,the bearing capacity of the ultra-soft foundation... |
