利用液压应力计直接测定软岩应力的模型试验研究

A Experimental Study of Directly Measurement of Stress in Weak Rockmass by Means of Hydraulic Boring Stressometer

通过对各种地应力测量方法的对比研究,格鲁兹(Glotzi)压力盒的考查,模拟材料的试验研究,和CYG-00型液压应力计与试件加压方向成不同夹角(0°、45°、90°)的模拟试验,我们首次提出了采用“液压钻孔应力计”直接测定软岩应力的方法和原理。本文介绍液压钻孔应力计的结构原理、使用方法和模拟试验结果。

In this paper, we performed contrast analysis of various kinds of geostress measuring methods, and inspected Glotzi pressure cell. On three directions (0°, 45°, 90°), the modellings of stress measurements were conducted with CYG-00 hydraulic stressometer.We firstly suggested the method of directly measuring stress in weak rockmass with hydraulic boring stressometer. which consisted of three hydraulic stressometer.The structure principle and operating method of hydraulic boring stressometer were introduced. In addition, some modelling results of stress measurement with this stressometer were presented.
