Liquefaction Evaluation of Microbial Induced Calcium Carbonate Precipitation (MICP) Treated Sands; A Strain Energy Approach

Baziar, Mohammad Hassan / Alibolandi, Mahdi

The present research investigates liquefaction behavior of microbial induced calcium carbonate precipitation (MICP)-treated Nevada sand with different silt content, for the first time in terms of dissipated strain energy. The obtained results indicated that normalized liquefaction capacity energy for MICP-treated soil was dependent on the CSR and N_L. Moreover, acceptable relationships between the excess pore water pressure ratio and dissipated energy were found for both MICP-treated and untreated samples. Furthermore, Bender element tests results proved that shear wave velocities had a stronger relationship with rather than CSR, while, MICP treatment changed the relationship between and liquefaction resistance.
