| Abstract: | The special loads during many special transportations such as in the construction of the power house overstep the scope of the carrying capacity of those former stone arch bridges that were designed for general loads.Taking Shahe Bridge as an example,the composite strengthening for stone arch bridges by pouring reinforced concrete that steel wire net and steel fiber included(3-steel concrete for short) and sticking steel plate is presented,and the trailer with 240t loads was successfully transited. |
