The main goal of engineering geology for designing and construction complex structures in urban areas

Abstract

Work for designing complex structures in urban areas consists of geological-geotechnical investigations and analysis of the quality of rocks, soft rocks and hard soils in the construction area. Urban areas limited the space for designing cutting slopes in stable inclination without reinforcement. In this paper will be presented designing and excavation works with different reinforcement of two different areas in Slovenia built of heterogeneous mixed hard to soft rock masses (Triassic dolomite, limestone and Eocene flysch sediments). Before the start of excavations work and after establishing the retaining measures, the analysis results are checked by monitoring. This monitoring will continue in the phase of exploitation of the objects. Since the cost of these additional investigations and precise analysis with monitoring (SIST - EN 7 - 2004) and measurements is negligible - in comparison with the costs of the permanent reinforcement - if variable conditions are not to intensive, we were able to reduce effectively the investment value of the object.
