摘要

阵列式位移计（SAA）是一种基于微电子机械系统测试原理的测试加速度和位移的传感器，该方法具有精度高、可重复利用、自动实时采集等特点。介绍了SAA测试技术首次在成层土中桩基与复合桩基大型振动台模型试验中的应用，研究了桩基、复合地基及模型地基土体系的地震位移响应。试验结果表明：SAA可全面、直观地测试桩体及土体在地震动荷载下的加速度以及变形反应规律；测试数据发现小震作用下，地基土与桩身位移协调；随地震作用加大，地基土与桩身位移差异增大；地基土中软土夹层的存在对地基土的水平位移影响较大。

Abstract

Shape acceleration array (SAA) is a sensor based on microelectronic mechanical system (MEMS) testing principle used to test acceleration and displacement

and it has the characteristics of high accuracy

reusable

automatic real-time acquisition. This paper presents the first use of the shape-acceleration array (SAA) technology in shaking table test of pile and composite subgrade in layered soils. We investigate the displacement response of the coupling system of pile and composite subgrade as well as soils under seismic excitations. Experimental results show that SAA can record the dynamic behavior of piles and soils in regard to accelerations and deformations. We also observe that the deformations of piles and soils are compatible only under small amplitude earthquakes. The existence of soft soil layers has a large effect on the horizontal displacement of the soil foundation.
