摘　　要：从电液伺服岩石压力试验机工作机理的角度,对目前岩石应力-应变全过程曲线(以下简称“全曲线”)测试中的一些问题进行了分析,提出了自己的看法,目的是为了解决“全曲线”测试的2个问题,即如何测出“全曲线”;如何使测出的“全曲线”真实反映岩石的力学特性,并将其用到工程中。From the point of mechanism of an electrohydraulic servo controlled rock pressure testing machine, some problems met when determining the curve of complete rock stress-strain process (hereinafter, complete curve) are analyzed and corresponding views are given. The solution of how to determine complete curve and how to make the determined complete curve factually reflects rock mechanical properties is also provided. This solution can be applied to practical engineering.
