The precise assessment of intact rock strength is fundamental for the safe design of geotechnical structures such as tunnels and foundations. While Uniaxial Compressive Strength (UCS) is a primary mechanical parameter, its direct measurement is often costly and time-consuming. The Point Load Strength Index (PLSI) test offers a practical indirect alternative; however, its reliability is significantly influenced by the anisotropic nature of sedimentary rocks. This research investigates the directional dependency of compressive strength in layered rock formations. Core samples were collected from the Soran City Cable Car region (Bapshtian) in the Kurdistan Region of Iraq, specifically from a zone characterized by distinct bedding planes. The methodology involves continuous wireline coring to retrieve specimens from both vertical (90°) and inclined (60°) boreholes. Using an automated, servo-controlled AZMOON (Model: JQ-EJ9) testing system, the specimens are subjected to axial and diametral loading configurations relative to the bedding planes. The study aims to establish a more accurate correlation between the point load index (I_{s50}) and UCS by quantifying strength variations at different anisotropic angles. Preliminary analysis suggests that failure mechanisms are highly sensitive to the orientation of applied stress. The final results are expected to provide a robust empirical framework for predicting the mechanical performance of anisotropic rock masses in the region, thereby enhancing the reliability of indirect strength estimation techniques in geotechnical engineering practice.
