Abstract:
Based on the typical design and construction cases of shaking table at home and abroad, first, the classification of shaking table foundation structure was summarized, and that the vibration intensity, structural form and actual site conditions should be comprehensively considered for selection was put forward in this paper. Second, the influences of some key parameters on the characteristics of shaking table system, e.g., the foundation quality should not be blindly increased in design, and the comprehensive design should be combined with the structural form, were analyzed. Third, three kinds of dynamic calculation methods of shaking table foundation, including GB 50040—96 method, Foundation Engineering Handbook method and Lysmer method, were compared, and the applicability of each method was summarized; Finally, the key problems that should be considered in the construction process of shaking table foundation, including mass concrete cracking, foundation pit support and embedded parts installation accuracy were summarized, and suggestions were put forward.
