A methodology for road cutting design guidelines based on field observations

Road networks in low and lower-middle income countries (LIC/LMICs) are rapidly expanding to enhance social economic growth. The construction of a new road often requires cuttings be made, especially hilly topography. In LIC/LMICs, many practitioners rely on guidelines design roadside cuttings, however, some these lack accuracy as they not developed using rigorous stability analysis methods. Stability charts offer more reliable alternative guidelines; difficult use the field. To overcome this gap, we present methodology develop user-friendly for preliminary cuttings. failure criteria commonly employed by (i.e. Generalised-Hoek-Brown rock Mohr-Coulomb soil) Limit Equilibrium Method, Morgenstern-Price, analyses. addition, consider upslope geometric boundary conditions slope seepage. designed including categories with accessible descriptions characterise material geometry that can selected practitioner Then is showcased producing Nepal Ethiopia. We believe systematic following novel here illustrated will reduce error, thus lead increased life span.
