Abstract
This paper investigates the benefits of using reinforced soil foundations to improve the bearing pressure of shallow foundations on soil using numerical methods. Numerical study of geogrid reinforced soil involves estimation and validation of geogrid properties. Reliability-based design of reinforced soil foundation is performed using kriging surrogates. It involves calibrating and validating a kriging model using samples generated by any deterministic geotechnical numerical model. Surrogate models simplify probabilistic computations and Monte Carlo Simulations. The design methodology is applied for a shallow foundation on soils reinforced with multiple geogrid layers. Results demonstrate the possibilities of surrogate modelling to design geogrid reinforced soil foundations and their capability to reduce settlement and improve bearing capacity, thereby reducing foundation area.
期刊介绍：
An online only, rapid publication journal, Geosynthetics International – an official journal of the International Geosynthetics Society (IGS) – publishes the best information on current geosynthetics technology in research, design innovation, new materials and construction practice.
Topics covered
The whole of geosynthetic materials (including natural fibre products) such as research, behaviour, performance analysis, testing, design, construction methods, case histories and field experience. Geosynthetics International is received by all members of the IGS as part of their membership, and is published in e-only format six times a year.
