Large-scale shear box of simple shear type

This laboratory is equipped with a large scale test facility, for soil-structure dynamics such as earth pressure problems. A large-scale shear box (5mX4mX10m) equipped in one of the laboratory's five large underground pits (depth:6m) reproduces the ground vibrations generated during earthquakes. A testing box (F=1.5m, W=3m) capable of dynamic and static leading is also equipped to reproduce stress Conditions under deep ground for the development of techniques for ground surveys, etc. Utilizing an artificial rainfall apparatus, rainfall testing conducted at rainfall intensities of up to 150mm/h is useful for solving the problems of earth pressure during rainfall. In the pit reproducing soft ground, the soft ground subsidence of a full-scale house can be tested.
