【摘要】:針對滑坡路段公路線形設計的復雜性及不確定性,在充分考慮地質資料、施工條件、工程經濟及環(huán)境影響等因素的基礎上,構造多種線形方案,利用熵權決策法對各方案進行比選,根據(jù)各方案與理想點的貼近度對方案排序,從而選出最優(yōu)方案。通過對永藍高速某滑坡處公路線形方案比選,證明該方法具有簡便、定量、嚴密和識別評判能力較強的特點。
[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.
