| Abstract: | Aiming at solving the problems of expressways being blocked either as a result of war,terrorist attacks,natural disaster,or other emergencies,and the heavy traffic on the expressways being unable to be diverted within a short period of time,a new type of bridge-equipment for emergency diversion is studied and designed.The bridge-equipment is made mainly of GFRP,and the whole bridge adopts the simple supporting system.Its basic structural style is of the assembling structure,with its deck structure being made up of GFRP tubes,its lower truss structure being made up of standardized section truss structure and its front and end section truss structures.The reliability of the bridge deck and the truss structure is examined and proved with the ANSYS software.Being light in weight,simple and easy in operation and satisfactory in economy,the equipment can meet the requirements of emergency diversion.It may ensure the rapid diversion of light-duty vehicles from expressways. |
