Study On Mountain Road Cargo Transportation

In recent years,with the rapid development of social economy,the country large-scale development of large hydropower station,the new large and medium-sized chemical factory construction project and the West East electricity transmission project and other major infrastructure construction projects,these projects often require heavy and large equipment long distance transport,these equipment in the domestic production,someproduction in foreign countries according to the production equipment,transportation route location and use different place some of the railway transport to road transport,some of the port after landing of highway transportation,basic must pass through the road transport.Because thereinforcement cost,large transport with low grade highway transportation,low grade highway route alignment error,slope,bridge bearing capacity is low,to large transport,must solve the technical problems of large equipment transport vehicle turning minimum radius,climbing slope,trafficspace and the bearing capacity of the bridge.But in the implementation process,the reinforcement of bridge became the key control engineering.Large transport bridge reinforcement,different from the disease of bridgereinforcement,mainly to the needs of large transport,large transportthrough times less,load level,the combination of these transportcharacteristics of the bridge are presented,along with the type oftransformation and reinforcement scheme,at the same time,also need to take into account the traffic problem in reinforcement process in the part of the transformation of national and provincial highway.Road and Bridge Engineering in this paper,a total length of 522 kilometers of large transportation project as the background,analysis of the whole road transportation for renovation and reinforcement of bridge,the bridge and several typical(small span stone arch bridge,the Jian Zhiliang bridge)research methods of treatment,but also the bridge simulation test is carried out,the targeted solutions.The results of the research,it has good application value and reference value.
