地下建筑防火（Underground building fire protection） Discussion on fire protection design of underground buildings Chen Minggang Abstract: this paper discusses some problems about the design of fire protection in underground buildings, and summarizes some problems that should be paid attention to in fire control design. Key words: underground building fire prevention, smoke - proof partition safety evacuation decoration materials not combustible Underground construction fire work should pay attention to the fire prevention and early fire fighting, based on the improvement of fire prevention facilities inside the building. Therefore, in the underground fire prevention design needs to consider a lot of problems, such as general layout, the structure of the refractory grade, fire zone, fire separation, safe evacuation, fire water, ventilation, air conditioning and electrical appliances such as fire prevention. At the same time, according to the characteristics of underground fire, a series of fire control measures are taken to control the fire source, control fire development, safety evacuation, automatic fire alarm and fire extinguishing equipment. The following main problems should be considered in the design of fire prevention in underground buildings: I. the use and construction scale of underground buildings 1. The overall plane design of underground buildings should be based on the overall plan of the city, and reasonably determine its location, fireproof spacing, fire prevention channel and water supply. 2. The production and storage of products of a and b shall not be located in the underground building, which is stipulated in the current building design fire protection code of our country. In the fire prevention code of civil air defense engineering, it also stipulates that there should be no high pressure boiler room, ammonia freezing station and a production workshop, and the goods warehouse. Liquid petroleum gas and liquids less than 60 degrees are strictly prohib
