Microbially Induced Carbonate Precipitation Process for Soil Improvement Adjacent to Model Pile by Innovative Delivery System
Microbially induced carbonate precipitation (MICP) is an innovative approach to improve loose soil using bacteria to hydrolyze urea and facilitate the precipitation of calcium carbonate. In this paper, a proposed double wall pile delivery system is introduced to improve submerged sand adjacent to a pile foundation system using MICP. The implementation of MICP delivery system was conducted via the double wall model pile under various constant head differentials in a large-scale soil box. The level of cementation was spatially monitored during treatment using bender elements for shear wave velocity measurements. After the completion of the treatment, cone tip resistance was measured to assess the improvement with distance from the injection source. The cementation profile was also assessed by acid washing the treated sand at key locations. Stabilization results based on the use of the proposed double wall pile delivery system and associated challenges are presented and discussed.
