    In this paper, we numerically analyze a 9.0-m-tall reinforced soil retaining wall in a platform embankment, simulating the behaviour of its various components by using software and material models. The two basic constituents of the structure are the fill material and reinforcement. The designed reinforced soil retaining wall was built using local materials (sand with fine particles) on a base of sandy gravel. The design was analyzed with various software packages such as TensarSoil, Slide, and Plaxis 2D. The results show that the wall meets the requirements for both static and seismic conditions

    Lime stabilization as a method for soil improvement is beneficial for number of important engineering properties, such as: strength, resistance to fracture, resilient properties and reduced swelling. This paper briefly describes the application of quicklime to stabilize soft soil. Many laboratory tests have been carried out on silty soil to determine the improvements for lime in varying percentages. The laboratory investigations for different lime contents preparing with optimum moisture content and sample curing under controlled conditions were carried out. The investigation of both treated and untreated soil are focused mainly on the strength parameters, changes in the plastic properties, compaction requirements, California Bearing Ratio and compressibility characteristics of the lime-soil mixtures. Significant improvement and stabilization of the silty soft soil has been observed for 4 percent of lime admixtures.

    Tunnels represent significant financial investments with challenging design, construction, and operational issues. They remain in service for extended periods of time, sometime beyond their intended service life. Hydrotechnical tunnels are often prone to repairs and rehabilitation because of the devastating effect of the water. The rehabilitation of any kind of tunnel is a complex process which involves knowledge and experts from different scientific areas. In this paper some experiences from the rehabilitation of the hydrotechnical tunnel on Saska River as a part of the mine for lead and zinc Sasa are shown.
