Abstract
The lift side anchor system for a 151 m span suspension bridge over river Alaknanda in Himalayan region was unstable. The gravity type anchor block for the suspension bridge was constructed by cutting the toe of the natural slope. Walls were constructed to retaining the backfill and the anchor block. Slips along the natural slope were frequent. The site lies in an active seismic zone.
The paper presents the details of analysis of anchor block, retaining walls and the natural slopes. The analysis is carried out both under static condition and also by taking seismic coefficients. The already constructed retaining walls which were unsafe have been strengthened by designing a composite retaining wall keeping in view the requirements of the client not to demolish any of the already constructed retaining wall.

Stability of Suspension Bridge Anchorage System
The lift side anchor system for a 151 m span suspension bridge over river Alaknanda in Himalayan region was unstable. The gravity type anchor block for the suspension bridge was constructed by cutting the toe of the natural slope. Walls were constructed to retaining the backfill and the anchor block. Slips along the natural slope were frequent. The site lies in an active seismic zone.
The paper presents the details of analysis of anchor block, retaining walls and the natural slopes. The analysis is carried out both under static condition and also by taking seismic coefficients. The already constructed retaining walls which were unsafe have been strengthened by designing a composite retaining wall keeping in view the requirements of the client not to demolish any of the already constructed retaining wall.
