Stability Evaluation and Mitigation Design of Transmission Towers on Slopes

Failure of transmission towers that constructed on slopes due to the excessive movement of slopes are frequently encountered. This paper presents a case history of stability remediation of a transmission tower on a slope with an objective of the enhancing the importance of the stability evaluation of the slope before the transmission tower construction. Based on the geological and geographical conditions at the project site, the failure modes of the slope are established, and the stability of the slope was evaluated with the commercial software Slope/W. The slope was then stabilized, and drainage measures were installed.

Abstract: Failure of transmission towers that constructed on slopes due to the excessive movement of slopes are frequently encountered. This paper presents a case history of stability remediation of a transmission tower on a slope with an objective of the enhancing the importance of the stability evaluation of the slope before the transmission tower construction. Based on the geological and geographical conditions at the project site, the failure modes of the slope are established, and the stability of the slope was evaluated with the commercial software Slope/W. The slope was then stabilized, and drainage measures were installed.
