In order to improve the anti-deformation and isolation ability of bridges under the action of vertical mining subsidence deformation in the mining areas,the control thoughts of double protection of anti-mining subsidence deformation and anti-seismic has been put forward.Firstly,basing on analyzing the principle of double protection of anti-mining subsidence deformation and anti-seismic of the bridge,we put forward a new type of isolation protection control device of anti-mining subsidence deformation and analyzed the protection principle of anti-mining deformation and anti-seismic.Secondly,we build the finite element model of a continuous slab bridge across three spans by the numerical analysis software to analyze and compare the vertical anti-deformation isolation effect of the double protection device under the coupled action of mining deformation and earthquake,and quantitatively analyze the damage degree of bridge structure caused by the mining subsidence and earthquake to put forward that double protection device of anti-deformation isolation can resist the damage of the bridge caused by coal mining effectively,and it can also decrease the dynamic response of the bridge caused by earthquake.The double protection device of anti-mining deformation subsidence deformation and anti-seismic can improve the performance of anti-mining and anti-seismic of bridge structure in mining area effectively,therefore it can provide scientific theory method and basis for mining bridge project safety construction and operation in our country.
