PILOT STUDY OF AN UNSTABLE SLOPE MANAGEMENT SYSTEM. FINAL TECHNICAL REPORT

Previously, an Unstable Slope Management System (USMS) had been developed to prioritize the repair of unstable slopes. This report describes the process of implementing and testing the USMS. The original system was comprised of two parts, a database and programs that determined the priority ratings of the slopes. These components of the USMS were modified to create a system that was more user friendly and better able to prevent errors than the original USMS. During the course of the project changes were made as necessary to the programs or databases to correct for errors. Modifications to the USMS included upgrading the software used to create the USMS. The USMS was tested using data on actual slopes having various degrees of active failure located in District 4 of the Washington State Department of Transportation (WSDOT). District 4 was selected because it exhibits a wide variety of conditions applicable to the USMS. Sites were selected by WSDOT personnel who were familiar with the area. A total of thirty-nine failure sites were identified and entered into the USMS. A parametric study of the results was performed to determine the effect of changing of the weighting factors used.
