Comprehensive evaluation method for subway green construction in limited space

Abstract

The invention discloses a comprehensive evaluation method for subway green construction in a limited space based on multi-objective analytic hierarchy process and grey correlation method, which comprises the following steps: firstly, performing hierarchical refinement on targets of subway green construction in the limited space, and establishing a hierarchical model of a construction scheme; secondly, employing authoritative experts in various fields to perform empirical judgment on the index weight of each level, establishing a judgment matrix, performing consistency judgment on the judgmentmatrix, and then calculating the relative weight of each index to the total target layer by using an analytic hierarchy process; determining the most ideal scheme according to the actual condition, constructing an evaluation matrix in combination with the to-be-evaluated scheme, performing normalization processing, and determining a reference and comparison sequence; and calculating the correlation degree of the comparison sequence and the reference sequence by using a grey correlation analysis method, and carrying out comprehensive evaluation according to the obtained analysis items. The evaluation method for subway green construction in the limited space is established in a targeted mode, and comprehensive evaluation of social, environmental, economic and other benefits is conducted on the subway green construction in the limited space.

Description

technical field [0001] The invention relates to an evaluation method for green construction, in particular to an evaluation for green construction of subways. Background technique [0002] With the acceleration of urbanization and the continuous growth of the population of large cities, urban rail transit has become the backbone of the urban transportation system by virtue of its large-capacity transportation services that are "fast, effective, safe, comfortable, environmentally friendly and energy-saving". Different from the construction process of ordinary projects, subway construction is usually carried out in dense living areas of the city. The entire construction process is strictly confined to a restricted space, that is, an overpass with a large traffic flow on the upper part, and the surrounding area is close to commercial and residential areas, and even There may also be key cultural relics protection units. Therefore, the subway construction has high requirements f...

Problems solved by technology

For example, the green construction evaluation system of Urumqi Metro proposed by Du Zhonghua et al. based on the entropy value method is relatively general and does not address the characteristics of subway construction well; the green construction evaluation system of Qingdao Metro Project proposed by Wang Min is aimed at the "soil-rock combination" of foundation pits characteristics without considering the impact of confined space

Therefore, at this stage, there is no effective method and scientific standard to measure the green construction level of the subway in the confined space, and it is necessary to study a comprehensive and effective evaluation system to guide the green construction process of the subway in this special case.
