对全长固定式锚杆作拉拔实验.典型的位移—载荷实测曲线见图1.图中曲线由四段曲线组合而成.1.OA段为斜直线;2.AB段是较为平缓的曲线;3.BC段为急剧变化的曲线;4.CD段为平行于位移轴的直线.本文的目的就是要从理论上说明上述四段曲线的力学意义.
Pull the whole length of the fixed anchor for experiment.Measured displacement - load measured curve shown in Figure 1. The curve is composed of four sections of curve combination .1.OA section is a straight line; 2.AB section is relatively flat Curve 3.BC section is a sharp curve 4.CD section is a straight line parallel to the axis of displacement The purpose of this paper is to theoretically explain the mechanical significance of the above four sections of the curve.
