| 摘要： | Three radius arch pipe composite bridges or culverts are provided under a roadway or railway as a cross drainage system carry over the stream or as an underground tunnel or as an animal pass structure. Three radius arch pipe culverts, a complex shaped pipe having three radii are using nowadays as a substitute to conventional type of culverts such as circular culvert and box culverts. In this study, the various geometrical and structural features of the arch pipe are investigated using the international codes Swedish standards, CHBDC (2014) and AASHTO LRFD (2017) and ASTM C 506 specification. The strength of pipe is evaluated by means of three edge bearing test. The three radius arch pipe is proven to the best owing to the advantages of its geometrical shape and hydraulic benefits compared to circular pipe and box culverts. |
