Measuring device for neutral point position of model pile
The invention discloses a measuring device for the neutral point position of a model pile. The measuring device comprises a model box body, a servo motor loading system, a displacement sensor fixing assembly, a pile body displacement measuring system, a pile periphery soil body settlement measuring system and a data processing system. The model box body comprises a model box, a model soil layer and a model pile. The servo motor loading system applies a vertical load to the model soil layer in the test process. The displacement sensor fixing assembly comprises a fixing beam and two fixing pipes, and the fixing pipes are fixedly connected to the bottom of the fixing beam and inserted into the model pile. The pile body displacement measuring system comprises a CMOS image sensor, a grating scale ruler and an illuminating lamp. The pile periphery soil body displacement measuring system comprises a magnetostriction displacement sensor and magnetic scrap iron. The data collection device is connected with the magnetostriction displacement sensor and the CMOS image sensor so as to collect displacement data in real time. The measuring device has the advantages that the displacement of the pile body and the soil body around the pile can be measured in a non-contact manner, so that the neutral point position of the pile foundation can be determined more accurately.
本发明公开了模型桩中性点位置的量测装置，包括模型箱体、伺服电机加载系统、位移传感器固定组件、桩身位移量测系统、桩周土体沉降量测系统和数据处理系统。模型箱体包括模型箱、模型土层和模型桩。伺服电机加载系统在试验过程中对模型土层施加竖向荷载。位移传感器固定组件包括固定梁和两固管，固管固接在固定梁底部且插入模型桩内部。桩身位移量测系统包括CMOS图像传感器、光栅刻度尺和照明灯。桩周土体位移量测系统包括磁致伸缩位移传感器和磁性碎铁屑。数据收集装置连接磁致伸缩位移传感器和CMOS图像传感器以实时收集位移数据。它具有如下优点：实现非接触式量测桩身和桩周土体位移，以能更加精准的确定桩基中性点位置。
