摘要：
Based on regular sawtooth joint specimens with four fluctuating angles,the shear tests under five normal stresses were carried out to get the test curve. The shear stress-shear displacement curves and different failure modes of joints were analyzed. The law of shear strength weakening stage was studied by using shear strength weakening ratio. It was concluded that when the normal stress is small and the undulation angle is large, the value of shear strength weakening ratio is larger, and it has a good linear relationship with the undulation angle.
