Evaluation of Stability Analysis Methods of Embankment on Soft Clays

Construction on soft clay deposits is assumed to be a significant concern in the geotechnical engineering field. Soft clays are characterized by low bearing capacity, high ductility and low permeability, which lead to certain constraints in embankment design. Therefore, to ensure the safety of structures on soft grounds, it is necessary to define the capacity that the foundation can bear before the construction process. In addition, the behaviour of a structure has to be predicted to avoid failures or other unfavourable circumstances that could take place in the future. A number of prediction methods have been proposed, but the predictions could suffer from a lack of accuracy, resulting in a lack of confidence in practice. In this study, numerical simulation of embankments on soft soils using finite element method (FEM) is performed, along with the evaluation of existing methods for predicting the performance of embankments on soft clays and to propose the most accurate stability analysis approach among reviewed methods

DESIGN STUDENT RESIDENCE BUILDING USING AERATED CONCRETE/BLOCK IN NAZARBAYEV UNIVERSITY, ASTANA, KAZAKHSTAN

This project is focused on the design of a student residence building using aerated concrete in Nazarbayev University, Astana, Kazakhstan. The shortage of residential places on the campus is one of the primary problems of the university. Thus, the design of the residence building for master students by DC Group is studied in this paper. Major part of the worldwide energy is consumed by residential and commercial buildings. Because of low thermal conductivity and light weight compared to normal concrete, aerated concrete is proposed in order to provide proper thermal insulation and prevent significant heat loss. Moreover, the project includes obtaining own mixture design through laboratory experiments, where aerated concrete blocks will be casted and tested for both mechanical and thermal properties
