Description
Technical Field
The invention relates to the technical field of building structure and equipment shock insulation, in particular to a three-dimensional shock insulation support integrating hydraulic self-recovery and limiting during earthquake early warning starting.
Background
The two main seismic zones in China, the Eurasian seismic zone and the Pacific seismic zone, are among the countries in the world which are most seriously harmed by earthquakes. Historically, severe earthquakes of more than 6 grades have occurred many times in Yangtze river delta and Zhu river delta, and in the Bohai area of Kyoto hoop, a major earthquake of more than 7 grades occurs every 55 years on average in nearly 300 years. With the acceleration of urbanization process, a great amount of national wealth is rapidly concentrated to cities and urban cluster areas. More than one third of established or proposed urban groups in China are located in areas where big earthquakes of more than 7 levels are likely to occur. The buildings which account for the vast majority of cities in China are reinforced concrete multi-storey and high-rise buildings which have wide use functions, and economic loss and casualties caused by the damage of the buildings cause great impact on national safety and social stability. The earthquake is that when the stratum of the earth crust is in a complex stress state and the action of the earth stress exceeds the ultimate strength of the stratum at a certain position along with the continuous change of the earth crust, the stratum can be suddenly broken and dislocated, so that the earthquake is caused, and is transmitted to the earth surface in the form of elastic waves, so that an object with certain mass near the earth surface generates inertia force, and when the self seismic capacity of the object for resisting the inertia action is insufficient, the object is damaged. When the excellent period of the local vibration is closer to the natural vibration period of the object, the damage of the object is more serious. The natural vibration period of the object can be obviously changed by arranging a certain vibration isolation device on the object, so that the excellent period of the earthquake is avoided, the inertia force acting on the object is obviously reduced, the damage of the object under the action of the earthquake is reduced, and the safety of the object under the earthquake is improved.
The seismic isolation technology essentially prolongs the natural vibration period of the structure by reducing the rigidity of the seismic isolation layer, so that the rigidity of the seismic isolation layer is generally low, the seismic isolation layer can deform greatly under the action of wind load, crowd load and other loads, and even can be seriously damaged in severe cases, so that the application of the seismic isolation technology also has limitation. Analyzing the time scale efficiency of the seismic isolation technology finds that only the short time of the seismic action actually really acts on the common seismic isolation technology, and more time does not act or even acts adversely. Therefore, the ideal seismic isolation technology should not work at ordinary times, only work temporarily when the earthquake happens, and stop working after the earthquake is over. The earthquake short-term forecasting and earthquake early warning technology brings application space for the application of the technology, and at the present stage, the earthquake short-term forecasting technology is extremely difficult to develop, but the earthquake early warning technology is developed vigorously, and after an earthquake occurs, the earthquake early warning technology can strive for precious but short time for earthquake defense setting by utilizing the principle that the light speed is faster than the earthquake wave speed, and the short time makes the transformation of the traditional earthquake isolation technology possible.
In addition, in many cases, because two buildings or two devices are relatively close to each other, the collision of two objects caused by vibration is caused by adjacent sides, and in many cases, the collision of the adjacent sides cannot be allowed, so that the deformation of the three-dimensional vibration isolation support needs to be limited, and particularly for objects moving at high speed like high-speed trains and the like, the collision between two rows of high-speed trains cannot be caused by the existence of the three-dimensional vibration isolation support. The three-dimensional shock insulation support can be used for relieving vibration generated by equipment or structures at ordinary times, and the vertical displacement is restrained and released for vibration insulation, so that the support is required to be allowed to displace to some extent in the vertical direction, a certain vibration insulation effect is achieved at ordinary times, but large deformation under the load action of wind load and the like is not allowed. In addition, the three-dimensional seismic isolation support also has residual plastic deformation under the action of strong shock, which affects the normal use of structures or equipment, for example, if a train has horizontal lateral residual deformation, the train is difficult to enter a station, and the risk of collision is also caused.
