该文简要说明了滑动测微计在桩身内力测试中的工作原理及资料处理方法。通过工程实例,分析桩身受荷时弹性模量随应变的变化规律,计算出各级荷载作用下桩身内力分布情况,并运用Matlab语言进行编程,绘制出各地层的桩侧摩阻力和端阻力等三维图形,为工程设计提供依据。 This paper briefly describes the working principles and data processing methods of the sliding micrometer in the pile internal force testing. Through the engineering example, the change law of the elastic modulus with the strain when the pile is subjected to load is analyzed, and the internal force distribution of the pile body under various loads is calculated. The friction and pile resistance And other three-dimensional graphics, provide the basis for engineering design.
