Abstract

The gravel cushion is a certain thickness of gravel layer laid on the foundation, which is composed of uniform bulk materials and it has the characteristics of good compaction performance, high filling density, high shear strength, small deformation, high bearing capacity, etc. Satisfactory results were obtained in various fields of civil engineering. In the operation site of crawler cranes, such as some electric power projects and heavy-load accumulation sites, most of the foundations are also double-layer foundations that have been replaced. However, the stress distribution and load-bearing performance of the double-layer foundation under the crawler crane operation need to be further studied. In this study, the QUY80 crawler crane was simplified into uniformly distributed loads on adjacent rectangles of equal size on the foundation. The finite difference FLAC3D software was used to establish a three-dimensional foundation model. For analysis.
