The invention discloses a slope model experimental method and system for researching an exploitation and blasting dynamic instability mechanism from an open pit to underground. The method comprises the following steps of manufacturing of an experimental model; loading of the experimental model, wherein an initial stress condition and different blasting vibration simulating loads of an experimentaltest block are loaded; model experiment testing. The system comprises a model manufacturing system, a model loading system and a structural plane shearing resistance strength test system, the model manufacturing system comprises an upper-lower side rock surrounding mold, a similar upper-side rock surrounding material, a similar lower-side rock surrounding material and an experimental model frame;the model loading system comprises an experimental test block initial stress state applying device and a blasting vibration simulating load applying device, and the structural plane shearing resistance strength test system comprises a stress control type shearing device, a lifting jack and a dial indicator. The slope model experimental method and system for the researching exploitation and blasting dynamic instability mechanism from the open pit to underground have the advantages that the aim of repeatable operability for simulating blasting vibration wave loading is achieved, and the attenuation law of the shearing resistance strength of the slope rock body structural plane under repeated blasting vibration effects can be objectively and visually reflected.

The invention relates to an architectural structural system, in particular to the structural system used for an ocean platform. A swing wall structural system comprises a main body piece, a connecting piece and a swing wall body. The bottom end of the main body piece is fixedly arranged on a ground base, the connecting piece is connected with a lateral surface of the main body piece and a lateral surface of the swing wall body respectively in a hinged mode, and the bottom end of the swing wall body is connected with the ground base in a hinged mode. The swing wall structure is capable of increasing the ability of a tube and frame type ocean platform structure to entirely resist an external load, greatly increasing abilities to resist the ice loading, the wave loading, the wind loading and the earthquake load, even the tsunami (lessons of the tsunami caused by a big earthquake in Japan in 2011 are painful and the ocean platform structure cannot be destroyed because of the destruction of a regional rod piece.
