This paper takes the construction of the main pier foundation pit support of a newly-built high-speed railway extra large bridge as an example.Taking into account the surrounding environment and hydrogeological conditions of the foundation pit,a comprehensive foundation pit support technology scheme was adopted,with reinforced concrete as the main body of the foundation pit support and Larson steel sheet piles for water sealing.The support structure was calculated and analyzed to ensure the safety of the construction technology scheme,while effectively saving construction costs.This study can provide some reference for the construction of foundation pits in similar bridge engineering.
