[0081] Implementation case: Maanshan Iron & Steel Co., Ltd. Port Raw Material Yard A ~ E material strip site upper fill layer is treated by dynamic compaction and piled up during the use of the material strip for many years. Due to environmental protection upgrades and intelligent transformation requirements, it is planned to build on the material strip C-shaped strips, C-shaped strips are particularly sensitive to settlement and deformation. For the C-shaped strip foundation design, it is necessary to provide the characteristic value of the bearing capacity and deformation modulus of the rammed (compacted) fill layer with a thickness of about 4m. Due to the tight construction period, the use of traditional load tests and on-site direct shear tests will consume a lot of time and financial resources. Therefore, the present invention is used in geotechnical engineering surveys to determine the characteristic value of the bearing capacity and deformation mode of the rammed (compacte...
