ABSTRACT
Reclamation on ultra-soft soil is extremely difficult due to its low strength and high compressibility. Slow and steady application of load is required in order to maintain the stability of the foundation. The method of reclamation on ultra-soft soil is described in this paper. Large settlement usually occurs which does not follow Terzaghi’s small strain theory. The large settlement which occurs in the initial stage of deformation does not lead to a gain in effective stress. This paper presents a case study of a reclamation and improvement of an ultra-soft soil and the deformation characteristic of the ultra-soft soil after reclamation.
