Abstract

Abstract

En 中文
• CIPP–polymer composite rehabilitation of corroded pipes with soil voids was assessed by full-scale tests and FE models. • A five-stage failure mechanism was identified, and rehabilitated fatigue life reached 2.1 times the unrepaired value. • An FE-assisted fatigue-life prediction method was developed for unrepaired and rehabilitated pipes.
