The paper presents a series of experimental studies on the anisotropic small strain stiffness of a biocemented glass sand. Multidirectional shear wave velocities were measured on the isotropic consolidated samples in a triaxial cell. The biotreatment method, shear wave velocity, and its anisotropy of the biocemented sand were reported. It is found that the shear wave velocity increases with the increase of cementation level and the stiffness anisotropy firstly increases then decreases with the increase of cementation level. The paper aims to provide a new way to simulate the undisturbed state of sandy soils in laboratory with the microbially induced calcite precipitation technique.
Key words: Shear wave velocity / biocementation / MICP / anisotropy
