[01] Constitutive Model Development of Cement-Based Treated Soil

PIC: Trihanyndio Rendy Satrya

Co.: Bambang Piscesa

Description:
This research focuses on the constitutive model development of cement-based treated soil. The cement-based treatment improves both the strength and the internal friction angle of the soil. The increase in strength clearly defines the improvement in the soil stiffness. To gain insight of the cement-based treated soil performance in slope stabilization, a full three-dimensional non-linear analysis should be carried out. However, the constitutive model of this cement-based treated soil need to be established. This research project consist of two phases. In the first phase, extensive literature review is carried out to identify the effectiveness of the treatment in terms of strengh and internal frictional angle from the available experimental test in the literature. In this phase, it is expected that the available data is sufficient, however, if more data is required, a new experimental research project will be open. In the second phase, a constitutive model is developed. Two failure surfaces such as Mohr-Coulomb and Drucker-Prager are investigated. The non-associativity behavior of the cement-treated based soil are examined. The constitutive model formulation is implemented inside COMPLAST software and is compared with the available test results.

Allocation:
-[01-A] One undergraduate student (S1) is required for the first phase. Good understanding in soil mechanics is required. Expected project time is one to two semester. [Status: Open]
-[01-B] One undergraduate student (S1) is required for the second phase. Good understanding in soil mechanics and experience coding in MatLab are required. [Status: Closed, waiting for 01-A]
Note: One Master student can take the research project as a whole with a minimum requirements stated in point [01-A] and [01-B]. Project 01-A must be completed first before 01-B project is available.
