Aanalyse on the Causation and Classification of Usual Damages of Highway Tunnel

Abstract:

There are long spans and various types of lining of highway tunnels under different geological conditions. It is challenging to obtain accurate geological condition data of tunnel, the existing tunnel design theories and methods are not mature either. Meantime, the stresses of tunnel during the stage of design, construction, operation and maintenance are also changing with time. Therefore, it is difficult to discover the root causes of the highway tunnels defeats, also because of the joint influence of the above factors. Through the broadly investigations of defeats of highway tunnel, the reasons of these defeats was analyzed and classified from four aspects, external forces, design methods, construction phase and deterioration of materials. More important, the general rules and association between the defeats and causes was studied and suggested following the brief introduction of the highway tunnel defeats.
