Abstract

Microbial-induced calcite precipitation (MICP) is new upcoming method of ground improvement to increase strength and stiffness of soil. The improvement in soil occurs due to natural biogeochemical processes by introducing bacteria and cementation solution. This paper describes the application of eco-friendly MICP technique for improving unstable slopes. In the present study, unstable slopes (1H: 1V and 0.67H: 1V) were treated using bacteria (S. Pasteurii) and cementation solution (CaCl2 + Urea) at 2M concentration. The treated slopes were tested in a laboratory by conducting a model load test on slopes. The slope was treated by injecting MICP in a grid pattern of 50 mm x 50 mm. These unstable slopes were allowed to cure for the incubation period of 14 and 28 days. The results indicated that the unstable slope can be made stable after MICP treatment.
