摘要
在研究国内外隧道洞口景观概念及评价方法的基础上,提出隧道洞口绿色景观概念,认为隧道洞口景观应是在全生命周期的视野下关注其结构安全性、艺术性、经济性和生态安全性。确定了隧道洞口绿色景观包括洞门、洞口伸出物、洞口周边施工建设涉及到的山体、洞口延伸段及其绿化等内容,建立了包括目标层、准则层和指标层的3层隧道洞口绿色景观评价体系。运用该体系对隧道洞口景观工程进行评价时,可采用AHP法确定指标层权重向量,根据模糊数学理论确定隶属矩阵,最后通过矩阵运算对隧道洞口绿色景观进行两级评价,并根据其综合评价得分按最近原则进行等级划分。
On the basis of study on the concepts of domestic and overseas tunnel entrance landscape and the evaluation methods, the concept of green tunnel entrance land.scape was brought forward with consideration of safety, artistry, economy and zoology safety of tunnel structure in the eye shot of its whole lifecycle. The green tunnel entrance landscape comprises tunnel entrance, extention structure of tunnel entrance, the mountain around the tunnel entrance, the extend segment of tunnel entrance and their greening, etc. A three-layer evaluation system of green tunnel entrance landscape, including aim layer, rule layer and index layer, was established. When using the system to evaluate a tunnel entrance landscape, weight factor vectors can be obtained by AHP method, membership matrixes can be gained according to the fuzzy mathematical theory, two-grade evaluation of green tunnel entrance landscape can be given by means of matrix operations, and the grade of landscape can be determined by its synthetic evaluation score and the nearest rule.
