【 摘 要 】

The direct cause of the collapse of granary is irregular design, old breakage, lack of routine maintenance, and improper operation in the process of staff operation. The indirect reason for the collapse of granary is the customary operation of staff. If the grain height exceeds the grain line, it goes beyond the capacity allowed by the warehouse design, overloading the grain, and its side pressure exceeds the strength that the wall can bear, resulting in cracks and even collapse in the wall of the bungalow, which eventually leads to the occurrence of a buried accident. A granary was built in the 80s of last century, and it collapsed in the process of stacking grain. This paper analyzes the causes of collapse from the aspect of stress, according to the exploration situation, the actual calculation model is determined and the force calculation is carried out. The calculation parameters should be collected in force analysis, including: section size, strength, load and structural layout.
