This study investigates the deformation behavior of layered sedimentary rocks with diverse geotechnical properties under large-scale lateral loading conditions. These loads, primarily induced by tectonic activities, significantly alter the stress-strain distribution in geotechnical structures such as tunnels and roads built on slopes. Understanding these deformations is crucial for assessing the stability and performance of such structures. To analyze these effects, a series of controlled laboratory experiments were conducted using a specialized testing device designed to simulate lateral loading scenarios. The device measures layer deformations in meganeutons per square meter, providing precise insights into the mechanical response of bedded rock formations. The experimental setup involved systematically applying varying lateral loads while monitoring deformation patterns in different sedimentary rock samples. The recorded results highlight how weak sedimentary rocks respond to stress redistribution and lateral forces. The findings reveal critical deformation trends, structural weaknesses, and failure mechanisms that influence the long-term stability of geotechnical structures. This research contributes to a better understanding of the lateral load effects on layered rock formations and provides valuable data for designing more resilient infrastructure in geologically active regions.
