“…Researches [30][31] have shown that the greater the persistence is, the lower the shear strength of potential slip surface is, which means that the rock slope is more vulnerable to damage. According to this principle, the potential slip surface with the maximum persistence can be regarded as the critical slip surface.…”

Determining the critical slip surface of a fractured rock slope remains a major challenge. This study proposes a new method to determine the critical slip surface of fractured rock slope by comprehensively considering fracture characteristics. First, 2D fracture network of main sliding surface is simulated according to the characteristics of fractures on exposed rock surface. Then, potential slip surfaces between different entry and exit points on the main sliding surface are searched by Floyd algorithm. Finally, persistence, i.e. the percentage of total fracture length to the length of potential slip surface, is applied to evaluate the final critical slip surface. According to the above method, the final critical slip surface of a case study was determined, which show that the coordinates of the entry and exit points of the critical slip surface for the fractured rock slope are (62, 86 m) and (14, 30 m), respectively, with the persistence of 85.27 %.

We have studied the basic polarization properties of variously shaped lenses for the on-axis beam in the exit pupil and present the data obtained. The Mueller calculus and three-dimensional polarization calculus methods were applied for polarization ray tracing. The calculation methods were compared on different samples. We have demonstrated that taking into account the shape of lenses when designing lens optical systems contributes to the minimization of the diattenuation magnitude.
