The Application of Improved Efficiency Coefficient Method in Debris Flow Warning with Rock Technology in Civil Engineering
Xiangping Hu, Guo Yong Huang · Applied Mechanics and Materials · 2013
To solve the problem of inaccurate prediction of debris flow in dangerous rock technology, introducing combination weighting method to improve the accuracy. Calculate the weight of each impact factors by using improved AHP (analytical hierarchy process) and entropy method. Then use combination weighting method to put the two sets of weight into a new weight. Finally apply efficacy coefficient method quantitative assessment the risk of the debris flow. The instance results show: using Efficacy Coefficient method that combined the Combination Weighting method can reflect the actual situation of debris flows, and have better effect than using entropy method. And it provides an idea of the method on disaster prevention and mitigation and dangerous rock technology.
