Shahe Bridge Broaden Reinforcement Technology

This paper based on the common methods and outcomes of bridge reinforce in our country before, it researched double-arched-bridge combining with the actual distribution of bridges in Liaoning province. The purpose is to complete the reinforcement as the same time widening , that is, complete the improvement of loading dint through widening, so we can sum up a series of methods about designing, construction, checkup acceptance and apply for the highway construction in our province, thereby we can accelerate the rebuilding of the old double-arched-bridge in our province, and achieving the high-norm, high-quality, high-profit, so can it accumulation experience and build the basement for our province's bridge construction.This text has not been researched widely abroad, Liaoning province found a nation since then, especially since the 1960s, fixing set upping large quantity vapor-13, vapor-15 double-arched- bridge, now these bridges regardless on the loading ability and technique appearance, can't all and far adapt to today request, need the widening urgently to reform with reinforce. At the same time, also provided the abundant engineering to rely on, make to study the work for the research of this thesis can smoothly progress.
