The contributions of the current analytical models on the prediction of the stability of the slope subjected to slide head toppling failure mechanisms, have always focused on the idealized geometry comprising regular blocks dipping into the slope face. Besides, the influence of groundwater and stabilizations from the lowermost block of the slope have been overlooked in the available literature. In this article, the analytical solutions that incorporates the kinematic mechanisms of the jointed rock slope under the influence of groundwater and stabilizing the lowermost block subjected to slide head toppling are derived based on the limit equilibrium. Furthermore, a real slide head toppling failure case history was studied to illustrate the effectiveness of the presented analytical solutions. The investigation results indicate that the presence of groundwater in the jointed rock slope, lowers the distributions of the normal and shear forces thereby inducing slide head toppling. Reinforcing the lowermost block of the slope, enhances the distributions of the normal and shear forces thus improving the stability of the jointed rock slope. The study results depict that the presented analytical solutions can provide an accurate and efficient stability analyses of the jointed rock slope subjected to slide head toppling failure mechanisms considering the presence of groundwater and stabilization effects.

当前的分析模型对受滑头倾覆破坏机制影响的斜坡的稳定性的预测一直集中在理想的几何形状上，该几何形状包括浸入斜坡面的规则块。此外，现有文献中忽略了斜坡最下部的地下水和稳定作用的影响。在本文中，基于极限平衡，得出了结合了节理岩质边坡在地下水作用下的运动学机理和稳定受滑头倾覆影响的最下块的解析解。此外，还研究了真实的滑动头倾覆失败案例历史，以说明所提出的分析解决方案的有效性。研究结果表明，节理岩质边坡中存在地下水，降低了法向力和剪力的分布，从而导致滑头倾覆。加固斜坡的最下层，可增强法向力和剪力的分布，从而改善节理岩质边坡的稳定性。研究结果表明，考虑到地下水的存在和稳定作用，所提出的分析解决方案可以对受滑头倾覆破坏机制影响的节理岩质边坡提供准确而有效的稳定性分析。增强了法向力和剪力的分布，从而提高了节理岩质边坡的稳定性。研究结果表明，考虑到地下水的存在和稳定作用，所提出的分析解决方案可以对受滑头倾覆破坏机制影响的节理岩质边坡提供准确而有效的稳定性分析。增强了法向力和剪力的分布，从而提高了节理岩质边坡的稳定性。研究结果表明，考虑到地下水的存在和稳定作用，所提出的分析解决方案可以对受滑头倾覆破坏机制影响的节理岩质边坡提供准确而有效的稳定性分析。
