摘　　要：提出了利用Matlab软件来计算和绘制无铰拱内力影响线的方法,并给出了详细的步骤和具体的代码.通过Matlab的计算和绘图功能,可以简单快捷地对无铰拱结构的内力进行计算,并绘制出无铰拱结构任意截面的轴力、剪力、弯矩影响线以及拱脚处的反力影响线,同时还能求出影响线上任意点的量值.A method of calculating and drawing influential lines of internal forces of hingeless arch by Matlab is presented and detailed steps and specific codes are provided.Utilizing the calculation and drawing function of Matlab software,the internal forces of hingeless arch structure can be calculated easily and quickly and their any section influential lines of axial force,shearing force,bending moment and the constraint force of the arch springing section can be drawn,meanwhile the value of any point in influential line figures can be calculated.
