Abstract

As a new type of storage structure, the prefabricated steel plate-concrete underground silo can efficiently utilize underground space, save energy and reduce carbon emissions, and ensure a sealed low-temperature grain storage environment. The analysis of internal forces and displacements of the composite silo wall is one of the key technical issues that need to be addressed in the design of underground silos. This study adopts a combination of experimental and numerical simulation methods to analyze the mechanical properties of the silo wall under the most unfavorable working condition (empty silo) soil pressure load; it explores the influence of concrete strength, external waterproof steel plate thickness, and internal steel plate thickness on the stress and displacement of the silo wall. The results show that under the soil pressure load, the circumferential stress at the same height of a single silo wall varies little, with smaller values on both sides of the wall and larger values in the middle. The numerical analysis results are in good agreement with the experimental results, where the average errors between the experimental and simulated values of the circumferential stress of the internal steel plate and the circumferential reinforcement of the silo wall are 7.84% and 6.56%, respectively. Within the selected parameter range, concrete strength and internal steel plate thickness have a significant impact on the circumferential stress of the internal steel plate of the silo wall and the radial displacement of the silo wall, and suggestions for selecting parameters are provided. This study can provide a reference for the engineering design of steel plate-concrete underground silos.
