Kalliorakenteet

Kalliorakenteet refers to structures built within or upon rock formations. This broad category encompasses a variety of engineered projects, including tunnels, underground caverns, mines, and foundations for buildings or infrastructure that utilize the stability and strength of rock. The design and construction of kalliorakenteet are heavily influenced by the geological properties of the rock, such as its strength, permeability, and presence of fractures. Understanding these characteristics is crucial for ensuring the safety and longevity of the structure.

Common types of kalliorakenteet include transportation tunnels, such as railway and road tunnels, which are essential for overcoming geographical barriers. Underground storage facilities, for oil, gas, or waste, also rely on rock's natural containment properties. In urban environments, subway systems and underground parking garages are prominent examples. Furthermore, the mining industry extensively utilizes rock excavation for resource extraction, creating vast subterranean networks. The principles applied in kalliorakenteet construction are rooted in geotechnical engineering, rock mechanics, and often require specialized excavation techniques like drilling and blasting, or mechanical excavation. Environmental considerations, such as water management and potential impacts on groundwater, are also integral to the planning and execution of such projects.
