【摘要】：針對(duì)泥石流危險(xiǎn)性評(píng)價(jià)中權(quán)重和危險(xiǎn)度,基于改進(jìn)的組合賦權(quán)物元可拓評(píng)價(jià)模型,提出確定權(quán)重的優(yōu)化算法。首先,根據(jù)文獻(xiàn)分析泥石流危險(xiǎn)度的分級(jí)標(biāo)準(zhǔn),建立危險(xiǎn)度評(píng)價(jià)指標(biāo),然后結(jié)合可拓物元評(píng)價(jià)理論,針對(duì)可拓法各指標(biāo)權(quán)重確定的問(wèn)題,將層次分析法計(jì)算得到的主觀權(quán)重結(jié)合投影尋蹤法所得到的客觀權(quán)重通過(guò)距離函數(shù)進(jìn)行耦合,從而獲取各指標(biāo)最終的綜合權(quán)重,結(jié)合投影尋蹤法優(yōu)化蝙蝠算法進(jìn)行求解,形成泥石流評(píng)價(jià)的組合賦權(quán)物元可拓模型。最后,借助Mat lab語(yǔ)言,調(diào)用內(nèi)嵌工具箱和相應(yīng)數(shù)學(xué)函數(shù),編制程序得以實(shí)現(xiàn)。結(jié)合已有工程實(shí)例驗(yàn)證表明:危險(xiǎn)性評(píng)價(jià)與實(shí)際工程相符合,評(píng)價(jià)結(jié)果相對(duì)合理,具有一定的工程應(yīng)用價(jià)值。
[Abstract]:Aiming at the weight and risk degree of debris flow risk assessment, an optimization algorithm for determining the weight of debris flow is proposed based on the improved combinatorial weight matter-element extension evaluation model. First of all, according to the literature analysis of debris flow hazard classification standard, the risk evaluation index is established, and then combined with extension matter element evaluation theory, aiming at the extension method of the weight of each index to determine the problem, The subjective weight obtained by AHP combined with objective weight obtained by projection pursuit method is coupled by distance function to obtain the final comprehensive weight of each index, and the bat algorithm is optimized by projection pursuit method to solve the problem. Forming a combined weighted matter-element extension model for debris flow evaluation. Finally, with the help of Mat lab language, the embedded toolbox and the corresponding mathematical functions are called, and the program is realized. Combined with the existing engineering examples, it is shown that the risk assessment is in accordance with the actual project, the evaluation result is relatively reasonable, and it has certain engineering application value.
