基于阵列式位移计的钢管桩基模型试验研究
Model Test Study on Steel Pipe Pile Foundation Based on Shape Acceleration Array
摘要
Abstract
The shape acceleration array (SAA) is composed of a continuum of segments of an accelerometer comprising a micro-electro-mechanical system with high precision, automatic real-time acquisition, reusable and so on.The principle of SAA and its application in pile foundation model test for the first time was introduced.Three different aspect ratios and three different loading inclination angles were considered in the tests.Lateral load behavior under lateral load and the effect of aspect ratio and loading inclination angle were studied.The test results show that SAA can easily and visually monitor and record the displacement of pile under different lateral loads;the bearing capacity can be improved significantly by increasing the aspect ratio.The more nearly horizontal the loading direction, the greater the bearing capacity of the steel pipe pile foundation is.关键词
