Author(s) Vinayagamoothy Sivakumar* M. Catherine Moorhead† Shane Donohue‡ Colin J. Serridge§ Snehasis Tripathy∥ John McKinley* Ciaran Doherty¶ Abstract This paper presents the assessment of consolidation and creep settlements of an isolated circular footing...
Effects of Urease-producing Bacteria on Permeability and Strength Control for Sands
Authore(s) Authors: S. Ikoma* T. Hata* J. Yoneda† K. Yamamoto‡ Abstract In the ground improvement field, microbially induced carbonate precipitation (MICP) is a novel bio-based soil improvement technique. To apply this technique, the presence of an actual...
Stress–strain Behaviour of Bio-desaturated Sand Under Undrained Monotonic and Cyclic Loading
Author(s) Kangda Wang, Jian Chu† Shifan Wu‡ Jia He§ Abstract Microbial (or bio-) desaturation is a new method for mitigation of the liquefaction hazard of sand. In this paper, a series of monotonic and cyclic triaxial tests was performed on bio-desaturated...
