【摘要】:針對(duì)滑坡路段公路線形設(shè)計(jì)的復(fù)雜性及不確定性,在充分考慮地質(zhì)資料、施工條件、工程經(jīng)濟(jì)及環(huán)境影響等因素的基礎(chǔ)上,構(gòu)造多種線形方案,利用熵權(quán)決策法對(duì)各方案進(jìn)行比選,根據(jù)各方案與理想點(diǎn)的貼近度對(duì)方案排序,從而選出最優(yōu)方案。通過對(duì)永藍(lán)高速某滑坡處公路線形方案比選,證明該方法具有簡(jiǎn)便、定量、嚴(yán)密和識(shí)別評(píng)判能力較強(qiáng)的特點(diǎn)。
[Abstract]:In view of the complexity and uncertainty of highway alignment design in landslide section, on the basis of fully considering geological data, construction conditions, engineering economic and environmental effects, a variety of linear schemes are constructed. The entropy weight decision method is used to compare and select each scheme, and the optimal scheme is selected according to the degree of closeness between each scheme and the ideal point. By comparing and selecting the alignment scheme of a landslide in Yonglan Expressway, it is proved that the method is simple, quantitative, rigorous and has strong ability to identify and judge.
