Status and prospect of research on deformation resistance of frame structures in coal mining subsidence areas
China's mining cities are faced with the difficult problem of utilizing coal mining subsidence area land resources for engineering construction.On the basis of statistics of the development status of coal mining subsidence area,comprehensive treatment and its engineering construction utilization rate,the necessity of using coal mining subsidence area site for engineering construction is analyzed.The research and development history and shortcomings of the deformation damage and protection technology of frame structure buildings are summarized and analyzed from four aspects,such as the principle of deformation resistance of frame structures,the mechanism of common action,grouting reinforcement technology and building deformation resistance technology;and the development direction of deformation resistance technology of frame structure buildings is also prospected:dynamic evolution law of additional effect of large-span and multi-storey frame structure under surface movement deformation,mechanical behaviour and deformation synergy mechanism of foundation-foundation-structure joint action,new anti-deformation technology of frame structure building,and anti-seismic and anti-deformation regulation technology of frame structure building,so as to form a comprehensive theoretical and technical system of frame structure building under surface movement deformation and provide theoretical and technological support for the realization of the large-scale frame structure building construction and utilization of the coal mining subsidence area.
