Data Acquisition Technology of Large Scale Shaking Table Test of Subway Station Structure

Based on latest improvement of shaking table test of subway station structure, the paper carries out an experiment to verify the monitoring and data acquisition technology in the shaking table test. The test item mainly includes acceleration in the soil and on the structure, interaction force between soil and structure, distribution of soil displacement field, the relative displacement of structure to soil, and pore-water pressure. After analyzing the experiment process, the researchers find out several common difficulties that easy to meet in similar kind of tests, and also propose some solutions and ideas to handle with the difficulties.
