在三向应力状态下测定岩石抗剪力学性质的常规三轴试验,基于岩石或脆性材料破坏时剪切面上的极限平衡条件,τ= c+σtgφ。式中τ为抗剪强度;c为粘聚力;σ为正应力;φ为内摩擦角。c和φ值在岩体工程中是两个十分重要的指标。 通过岩石三轴试验,对原始数据整理、计算、绘图求得c、φ值的过程比较繁琐。为此编制了简便、省时、易于操作的pC-1500计算机RASIC语言计算、绘图程序。 Conventional triaxial tests for determining the mechanical properties of rock under triaxial stress are based on the limit equilibrium conditions on the shear surface when rock or brittle material is destroyed, τ = c + σtgφ. In the formula, τ is the shear strength; c is the cohesive force; σ is the normal stress; φ is the internal friction angle. The c and φ values ​​are two very important indicators in rock mass engineering. Through rock triaxial tests, the process of obtaining c, φ values ​​for collating, calculating, and drawing the original data is cumbersome. To this end, a simple, time-saving and easy-to-use pC-1500 computer RASIC language calculation and drawing program was developed.
