桩柱拖曳力系数测定的复摆法

Compouding Pendulum Method to Measure the Drag Coefficient of Pile

本文阐述了桩柱拖曳力系数测定的复摆法原理、实验装置及量测系统,并对三种不同直径的圆柱进行了拖曳力系数的测定,所得数据稳定可靠,从而验证了此法的可行性。这种方法测试装置简单,在桩柱拖曳力系数的研究中具有广泛的应用前景。

The theory, testing device and measuring system of compound pendulum method to obtain the drag coefficent of pile cylinder are discussed in this paper. Then the drag coefficents of three different diameter cylinders are measured. The practicabilty of this method is verified by the stabil- ity and the reliability of the data obtained. The test equipments of this method are simple. The prospect of applying this method in the study of drag coefficient of pile cylinder is bright.
