In order to promote the rapid construction technique of culvert,prefabricated culvert con-struction method,a rapid culvert construction method,is introduced.In this paper,the mechanical properties at the bonding area of the components are mainly studied,while the strength of two weak surfaces is also analyzed.The results suggest that the bonding surface of abutment cap and side wall of culvert should be bonded with C25 concrete or M30 cement mortar,and the depth that the side wall embedded into the base top surface,should not below 5 cm.
