摘要
可持续发展是当前21世纪人类共同的发展主题,对于城市公路研究来说必须要从传统高消耗型发展模式逐渐向高效蓝色型发展模式转变,绿色公路就是当今世界公路发展的一个必然趋势,并且,绿色公路建设作为国家迈向新时代的重要标志,其建设时期生态重建工作是一个不可回避的问题。就此,本文参照绿色公路设计相关规范要求,提出了利用BIM信息模型,通过BIM模型协助德尔菲法构建绿色公路生态重建预评价体系,再通过德尔菲法与层次分析法相结合的办法确定各指标权重,最后使用模糊综合评价出结果,依据最大隶属度原则确定评价等级,对黑龙江省绿色公路项目呼玛至十八站改扩建公路进行预评价,其预评价等级为“良好”。结果表明通过BIM模型的协助,评价机构可以更准确的了解绿色公路施工期状态,使生态重建评价体系和评价分数更为可靠,通过多种方法相结合的办法也有效地规避了单一方法带来的误差。绿色公路生态重建预评价体系的建立对于构建绿色公路全生命周期评价具有补充和完善的重要现实意义。
Sustainable development is the human beings in the 21st century the development of the theme,for urban road research is must be high consumption development pattern gradually from the traditional to the efficient blue type development mode change,green road is an inevitable trend in the development of highway in the world,and the green highway construction as an important symbol of country toward a new age,its construction period,ecological reconstruction is an unavoidable problem.In this article refer to green highway design specification requirements,using BIM information model is put forward,through the BIM model to assist the Delphi method to construct green highway ecological rehabilitation evaluation system,through the combination of Delphi method and analytic hierarchy process to determine the index weight,then using fuzzy comprehensive evaluation of the results,based on the principles of maximum membership degree evaluation level.The pre-evaluation of the highway reconstruction and expansion from Huma to Shiba station in Heilongjiang province was carried out,and the pre-evaluation grade was"good".The results show that with the assistance of BIM model,evaluation institutions can more accurately understand the status of green highway construction period,make the ecological reconstruction evaluation system and evaluation score more reliable,and effectively avoid the errors brought by a single method by combining multiple methods.The establishment of the pre-evaluation system for the ecological reconstruction of green highways is of great practical significance for the construction of the full life cycle evaluation of green highways.
