Abstract
The design and construction of large-span overhead jacking culvert beneath the existing railway with lower filling remains a technical problem. This paper deals with the scheme of overhead jacking which is a-dopted by Mianchi overpass of the extension project of Luosan highway. It elaborates a series of important procedures, such as the beam pier pile checking, jacking force calculation, jacking equipments, rail pile back design and the construction conditions etc. . This project therefore solves the technical problem of the key technology concerning the design and construction of large-span overhead jacking culvert beneath the existing railway. It provides theoretical foundation and project practice for similar type of projects and offers significant technological support for large-span overhead jacking culvert.关键词
