摘　　要：对静水压力下矩形平面和扇形柱面受力行为进行试验测量法实验研究,实验采用杠杆支点移动、力的分解及转换方法.实验结果表明:利用支点位移法,改进后的扇形柱面压力测量仪不仅具有静水压力下测量矩形平面受压测量功能,还增加了扇形体柱面受压测量功能;利用该实验量测法还能对水利工程中单调曲面进行高精度静压受力测量;同时,该实验量测方法用于高校水力学实验教学,能够丰富实验教学内容,有利于学生实践能力和创新能力的培养.The experimental investigation is on the hydrostatic pressure of rectangular plane and quadrant cylinder. The techniques of sliding pivot and mechanical transformation are used. The results show that the new designed apparatus has the advantage of measuring the quadrant cylinder pressure as well as measuring rectangle surface pressure. This method can also be used in accurate measurement of monotonic surface in hydrostatic pressure. At the same time,this measurement is suitable for the hydraulics experimental teaching. It produces more contents and forms in teaching and developing students’ability of innovation and practice.
