Investigation Of Design And Construction Of Single Direction Horizontal Shaking Table Foundation

By using shaking table test is a direct method to study earthquake response and failure mechanism of structure. Shaking table can simulate earthquake and perform related experiment. At present, the research about shaking table is focused on electro-hydraulic servo system, little on its foundation. This is a shortage of shaking table progress.Actually, foundation of shaking table is a mass that provide reaction to table movement and is an important part of the moving system. It is indispensable to study foundation of shaking table fully and deeply. This paper analyses an actual project, one 4mx4m single directional horizontal shaking table foundation, and studies its design and construction.In design process, beginning with the analysis basic theory of dynamical foundation, this paper calculates and analyses the foundation simply by hand and deeply by using Finit Element program. By comparing the two results, it presents a new half-in-ground model. After analyzing the fill, foundation dimension, material and reinforcing steel bar, the construction drawing can be obtained. During foundation construction, according to blueprint, some actual problems were solved include how to decrease mass concrete solidification quantity of heat and how to settle down construction joint. In addition, a transitional member was designed and the embedded parts were positioned accurately. It was proved that construction methods adopted were right in practice. At last, this paper introduces simply the design and construction of deep foundation shoring.The paper studies and summarizes the design and construction of foundation of shaking table. The study engineering is practical and provides reference for other shaking table construction.
