Abstract:A large-scale multifunctional structure experimental platform of 2 000t with a 10m×12m plane size and a 3-8m deep operation room was built in a present structure laboratory of South China University of Technology (SCUT). Combining with the structural analysis and experimental requirements, the key components of the extended anchorage platform of experimental platform and the steel-concrete bottom beam of the equipment were studied. Ground anchor system including both anchor hole and groove was adopted on the extended anchorage platform, and the construction of the lower foundation of the experimental platform was completed by reverse construction method to overcome the site restrictions, and the bottom steel beam components and the ground anchor system were successfully installed. The new experimental platform was combined with the original reaction frame to meet various experimental needs. It could provide reference for other universities and research institutes to build large scale structure experimental platforms.
