Slope Stability Analysis and Design Their Control Measures Dr. M. Kannan HOD CIVIL-PITS Arun Kumar Dept of CIVIL-PITS Abstract:- The incidences of slope failures are recurrent in Kathupparai hills in Bondinayakkanur, particularly along the Ghost road cutting and hill slopes carrying disruption in traffic, loss of life and damage to the property. This demand needs critical assessments of stability of slope along the hill roads. This research deals with stability analysis of soil slope at study area. A number of soil samples and slopes parameters have been collected, examined and studied; the orientation of discontinuities of slopes has been identified as one of the major inherent factors influencing slope instability along soil profile. As the laterite soil slope is mostly homogenous, limit equilibrium and circular failure charts methods were adopted for stability analysis of soil slopes based on height of slopes. That these methods are highly useful in determining the factor of safety in soil profiles and suggested recommendation for remedial measures. The outcome of this research exposed in the form of maps in GIS environment and suggested preventive measures in CAD design. This research would help planners and engineers in their assortments of the sites of their engineering projects and in the treatment of slopes that exists in critical state of stability. Keywords: Limit equilibrium, circular failure chart methods, factor of safety. I. INTRODUCTION Landslide is one of the important natural disasters, which commonly availed on cut slopes along Ghat section roads in mountainous region, while events are also reported in residential areas causing affects to human life, loss of properties, damage to established road network, and urban development in each year. Landslides also occur in natural slopes, influenced by various geo-environmental parameters and triggered by cloud precipitation, heavy rainfall, earthquake, etc. The natural slopes are converted into cut slopes by anthropogenic intervention for the purpose of transportation network, construction of dams, bridges, and tunnels are more prone to landslides occurrences in hilly terrain, landslides are natural denudation process and its occurrence is subjected to various causative factors and triggered by several inherent factors like lithology, structure, and exherent factors such as seismicity, rainfall, water level change, strom waves, and rapid stream erosion. Hill slopes in mountainous areas are affected by human activities such as building road network, urban development, deforestation, and rapid land use modification, may also influence occurrence of landslides. The stability of road cut highway slopes is always considered to be crucial as the slightest failure can be destructive in terms of monetary losses and harm to human lives. The cut slopes need to be carefully analyzed for this failure mechanism, prior to excavation, during excavation and post excavation. Slope stability analysis should be used to determine whether a proposed slope meets the required safety and performance criteria during design. This type of analysis is also utilized to determine stability conditions of existing natural or constructed slopes and evaluate the influence of proposed remedial methods if required. The project finding are expected to benefit civil and geotechnical engineers of government transportation agencies, conultants, and contractors dealing with slope stability, slope remediation, and geotechnical testing. A.PROBLEM DEFINITION Generally, the works of PWD and highway department are not in pre-planned way in the case of slope surfaces. When the process of vertical slope cutting or overturning of slope are done by means of using explosives such as dynamites, the slope failure occurs with time along the loading direction. So, we had taken the particular study as our project. Since 2007, the extension of the roads are being takes place. In this study area, we are planned to adopt the suitable control measures, based on soil and geotechnical parameters of the study area.
