Experiment Analysis on the Mechanical Properties of the Horizontally Stratified Mudstone

Abstract:

In order to analyze the physical and mechanical properties of the stratified mudstone, the specimens are collected from southwest Nanning , Guangxi, China. X-ray diffraction is used to analyze the mineral composition, the high montmorillonite content affects softening and expansion behavior of the mudstone. The strength tests show that the strength of stratified mudstone is low. When weakness layer exists in the mudstone, the strength is controlled by the soft layer. By long-term immersion in water, the strength will be approximately 76% to 85% reduction. The uniaxial compressive strength tests show that the ratio between soft layer and hard layer under natural is 0.17. The ratio between soft layer and hard layer under saturation is 0.10, under air seasoning is 0.42.
