  ABSTRACT: This study investigates the variations in shear strength parameters of red clay under different clay content and pH levels through direct shear tests. It analyzes the effects of normal stress, clay content, and pH on shear strength, cohesion, and the internal friction angle. The research reveals that with an increase in normal stress, the shear strength of the soil gradually increases under the same clay content and pH conditions. Under the same clay content, as the pH level becomes more acidic or alkaline, the shear strength of red clay decreases. Higher clay content in red clay results in greater shear strength under the same pH conditions. As pH becomes more acidic or alkaline, the internal friction angle and cohesion of red clay decrease under the same clay content. Compared to its effect on cohesion, pH has a more pronounced impact on the internal friction angle.
