| Abstract: | Pipeline jam accidents appear frequently during pumping construction of concrete of high-pier and long-span bridge, which result in not only great economic loss, but also serious delay of project completion. Based on the pipeline jam accidents appeared during the 13th high pier pumping construction of concrete for Fengshihe Bridge of Jishao Expressway and according to related codes, we make a careful analysis of the causes of pipeline jam, and put forward corresponding measures. The probability of pipeline jam accidents during pumping construction of concrete of high-pier and long-span bridge is calculated by the method of probability and statistics, and the key measures for reducing the pipeline jam accidents are pointed out. |
| Keywords: | high-pier and long-span bridge pumping construction of concrete pipeline jam accident probability analysis |
