Fire characteristics of the underground garages are analysed,and several problems concerning fire scale,critical smoke conditions for flashover,heat radiation,operating time of automatic sprinkler system and fire spread along card are investigated to study the fire risk of the underground garages.

Argues the different code about the smoke exhaust of underground garage in tall buildings between“Code for fire protection design of tall buildings”and “Code for fire protection design of garage, motor-repair-shop and parking-area”,Analysis the best design of the smoke exhaust.

It introduces the construction technology of underground curtain and reinforcedconcrete sheet surrounding protection structure for the underground garage project of Xiamen seashore, the economic & technical indices of which is compared with those of casting piledstructure for surrounding protection.

Ventilation design of the underground parking in the Lijing Garden apartment;

The analysis being in design to Ventilation and smoke exhaust Combine to be put into use of underground parking,Be summed up as Technology measure and specific Implementation plan in design to Ventilation and smoke exhaust Combine to be put into use of underground parking.

This paper introduces an intelligent management system of the underground parking,which is based on the advanced card technology,and the computer and network communication technology.

Air pollution and natural ventilation in underground car park;

The paper is given through the investigation into three underground car parks which locate in the north cities——Changchun,Shenyang,and Beijing.

As a part of the earth surface, the ground parking lot is one of the necessary traffic facilities in modern cities.
