| 摘要： | In case of construction of hill roads particularly in new alignment, construction of bridges remains a major challenge as number of rivers and streams cross the road alignment. Finalization of a bridge proposal across these water bodies in hilly areas, however need special attention to understand the hydraulic characteristics of the river, flood frequency and its extent, composition of the river bed material and that of hill slopes, alignment of approaches etc. However due to inaccessibility of site at DPR stage, such detailed study is not feasible during the initial survey. Therefore for establishing connectivity to develop areas remains a major challenge in new construction. Accordingly to address the issue effectively at initial stage, temporary bridges are planned and constructed across various water bodies which are replaced subsequently with permanent bridges in due course of time with proper load class and lane arrangement to ensure unrestricted traffic flow. To address the issue, Modular prefabricated quick launch steel bridges have been used extensively to abridge various gaps over the water bodies and establish proper connectivity to develop areas and progress further work. |
