- Abstract:
-
The design and construction of large-span overhead jacking culvert beneath the existing railway withlower filing remains a technical problem, This paper denls with the scheme of overhead jacking which is udopted 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 backdesign and the construction conditions etc. . This project therefore solves the technical problem of the key technology concering 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 significanttechnological support for large-span overhead jacking culvert.
