Study on facilities and technology of pile test in soft soil under extra-heavy load

In this paper,theories of geotechnical engineering, structure and steel structure are applied to study the short term bearing capacity of subsoil and combined loading method and the interforce, deformation, stability and coordinating function of modular beams in static loading test. And the safety measures which may be taken are also discussed. Meanwhile, a model of "carrying on the head-carrying on shoulders-bringing by hands" is given to solve some problems which exist in facilities and technology of extra heavy loading test of pile in soft soil.
