Abstract
The article presents selected scientific and technical problems referring to the construction and use of tunnels to ensure safety. The intensive development of tunnel construction technologies concerns the progress in their design. This progress is of particular importance for subsequent safe use. The priorities in the safe tunnels design procedure refer to the advanced methods and computational models and the awareness of the need of conducting geotechnical research. These tests cannot be limited to the normal activities such as determining the type of soil but must take into account many other aspects such as the optimal foundation depth, environmental impact, vibroacoustic, groundwater interference or the need to inventory existing buildings in the case of tunnel location in the built-up area. Incomplete recognition of the soil properties is the frequent reason for failures and disasters occurring during drilling and subsequent operation of tunnels. Previously performed tests are therefore the basis for minimizing the risk. Fire safety is another aspect of the article. The author presents examples of fire tests in tunnels carried out in recent years. Tunnel fire safety tests, including international projects such as the Eureka 499 "Firetun" and the Memorial Tunnel Fire Ventilation Test Program, were the first to provide reliable information on the nature and course of a tunnel fire. The article also presents the problem of ensuring adequate air quality inside the tunnel and the impact of pollutants resulting from fuel combustion on the human body. This section proposes ways to improve air quality in tunnels. The research includes specialized internal finishing coatings to reduce harmful substances such as NOx. The author presents the test results carried out in the Umberto I tunnel in Rome (Italy) before and after using the air-purifying coating/paint. The experiment showed over 20% reduction of NOx concentration, which is harmful to humans. The article presents essential subjects of safety in the stages of implementation and use of tunnels. The study refers to research and analyses focused on increasing the safety level.
