Experimental Study on the Bearing Performance of Segmented Prestressed Assembled Foundation with Full-Scale Testing

Year: 2025

Type: article

Abstract: This paper aims to address limitations of assembled foundations through a systematic approach involving the careful design and validation of precast foundations for transmission towers. Specifically, we introduce a novel method known as the Segmented Prestressed Assembled Foundation (SPAF), and demonstrate its application through a detailed design process based on an actual engineering project. Subsequent to the design phase, finite element models of both the proposed SPAF and conventional foundations are developed to facilitate a comprehensive comparison of their respective load-bearing performances. Furthermore, we conduct a full-scale test of the SPAF to verify the safety and efficacy of the newly proposed foundation design scheme. The results of our study indicate that the SPAF exhibits sufficient load-bearing performance comparable to that of a conventional cast-in-place foundation. Moreover, the inter-component connection method employed enhances the integrity of the SPAF, ensuring adequate joint strength and safety. Additionally, the SPAF offers significant advantages in terms of structural design and construction methods.
