САЖЕТАК / ABSTRACT:
Underground structures are often exposed to soil and water pressures, various aggressive chemicals, temperature variations, and the impact and vibrations of the equipment used. These often result in chemical attack on concrete, corrosion of steel reinforcing and loss of load-carrying capacity of the steel framing. To properly evaluate and repair underground structures, one has to apply a combination of geotechnical engineering, knowledge of materials and of structural engineering. Underground work requires special safety measures and training of workers and engineers. In addition to potential for dangerous gases and vertical fall hazards, the spaces to work in are very restricted. This paper present investigations and methods for repairs for typical mine shafts, tunnels and underpinning of building and bridge foundations. Types of deterioration are described, and various methods of repairs are presented.
