abstract="In order to study spatial-temporal exposure risks during cross operation in dam construction, firstly, disaster-causing situations of risk exposure were analyzed and dam construction processes were decomposed. Then, impact space of damage-energy processes and work space of hazard-affected processes were defined and a quantification model was proposed based on time distribution characteristics during cross operation and real-time location information of construction processes. Finally, with a hydropower station in southwest China as an example, simulation of construction processes in dam pouring was performed to determine duration and frequency of spatial-temporal exposure. The results show that total spatial-temporal exposure duration is 1 905 s while exposure frequency is 16. 85%, and risks are mainly from damage-energy processes, including horizontal deceleration and downward transportation with heavy-load, upward and horizontal acceleration transportation with no-load. © 2019 China Safety Science Journal.
