Abstract

The country’s largest cities are working intensively on the development of underground space in order to utilise their territory more fully and efficiently. Increase of fire hazard for people in underground space is determined both by the difficulties of evacuation of large masses of people of different mobility upwards, requiring, in particular, the use of means of vertical transport, and the peculiarities of the dynamics of CPF in a confined space. For designing of underground space objects with floor depth below 15m special technical specifications (STS) are developed. However, the authors of STS have no substantiated data for their development, as the scientific research necessary for their obtaining has not been carried out. Therefore, the supervisory authorities have no opportunity to analyse the degree of validity of the proposed solutions and the corresponding fire risk assessment. The article presents the results of research on the movement of people at metro stations through the “underground” type exit doors, allowing to assess the probability of crush formation during evacuation and to propose solutions to ensure unimpeded movement.
