Dynamic simulation of ground deformation based on animation
Ground deformation caused by groundwater exploitation,mine exploitation,deep foundation pit excavation,etc,seriously threatens normal production and life and structure safety of buildings,and the capacity of soil cultivation descends or abandons,so it is significance that studying defending and controlling methods of ground surface deformation.Because of the difficulty of reality expressing spatio-temporal characteristic and information of ground surface deformation,in order to solving the problem,it is need to adopt combining methods both spatial information technology and animation technology,and discusses the contents and ways of ground surface deformation dynamic simulation.Firstly,by means of ground surface deformation spatio-temporal course,the ground surface deformation spatio-temporal is founded.Secondly,on the basis of analyzing the time effect and space distribution characteristics of ground surface deformation caused by groundwater exploitation,mine exploitation,deep foundation pit excavation,the contents and ways of ground surface deformation dynamic simulation is founded.Finally,spatio-temporal characteristic of ground surface deformation is simulated by animation technology,digital terrain model and spatio-temporal database.The research shows that the dynamic simulation can nicely reflect spatio-temporal characteristics of ground surface deformation,and can expediently and rapidly study the laws of ground surface deformation.
