Malshej Ghat is one of the busiest transport corridors in Maharashtra. It is highly prone to landslides, as the region receives heavy precipitation and steep slopes along the road section. This manuscript focuses on the applicability and reliability of block size and shape classification techniques in the assessment of the stability of the road-cut rock slopes. Structurally weak zones extending along and across the road section are identified as a lineament, and accordingly, slopes are chosen for in-depth analysis. Kinematic analysis signifies that wedge failure is observed to be the most common type of failure, while planar and toppling failures are observed at places. The rock blocks which are produced as a result of the intersection of different joint sets are mainly cubic, cubic-elongated and elongated in shape, whereas platy, platy-cubic and elongated-platy blocks are very less in proportion. Volume and surface area of rock blocks play a vital role in the movement of the blocks. The rock mass is observed to be nearly poor to fair in quality; however, the numerical simulation shows that the slopes MRS-1, MRS-5, and MRS-7 are critically stable.

Malshej Ghat 是马哈拉施特拉邦最繁忙的交通走廊之一。由于该地区降水量大，路段坡度陡，因此很容易发生山体滑坡。本手稿重点关注块体尺寸和形状分类技术在路切岩石边坡稳定性评估中的适用性和可靠性。沿路段延伸和穿过路段的结构薄弱区域被识别为线条，相应地，选择坡度进行深入分析。运动学分析表明，楔形失效是最常见的失效类型，而平面失效和倾倒失效则在一些地方观察到。不同节理组交叉产生的岩块主要呈立方体、长方体和细长形，板状、板状立方体和细长板状块体所占比例很小。岩块的体积和表面积对其运动起着至关重要的作用。据观察，岩体的质量几乎为差到一般；然而，数值模拟表明斜率 MRS-1、MRS-5 和 MRS-7 是临界稳定的。
