Abstract: Based on the structural characteristics, engineering geological conditions and foundation treatment of large diameter spherical coal storage bunker in shaanxi coal preparation plant, a set of safety monitoring system for spherical coal storage bunker was established. The sensors are designed and arranged from composite foundation, ring foundation and underground passageway. This monitoring system can reflect the load change trend of spherical warehouse in construction period and operation period under the action of repeated pile of coal, coal unloading of stress and settlement of soil structure and the change trend of reinforced concrete spherical positions for gas film on the bearing capacity of foundation treatment, such as new structure design and material selection and so on to provide reliability, appropriate is used widely in the industry.
