裂隙在地下岩体中普遍存在,为了研究裂隙角度对岩石强度的影响,该试验采用与岩石相似的模型材料制作类岩石模型试样,通过在相似材料内预制裂隙来模拟不同裂隙角度的岩石,利用RMT150数控电液伺服试验系统测定不同裂隙角度类岩石材料强度。试验结果表明:试件的峰值强度随着裂隙角度的增大表现出先减小后增大的趋势,并在90°时达到最大。 In order to study the effect of crack angle on the strength of rock, a rock-like model specimen was made from a model material similar to the rock and a rock was simulated by prefabricated cracks in a similar material to simulate rocks with different crack angles. Using RMT150 Numerical Control Electro-hydraulic Servo Test System to Measure the Rock Material Strength at Different Slit Angle. The experimental results show that the peak strength of the specimen decreases first and then increases with the increase of the crack angle, and reaches the maximum at 90 °.
