【摘要】 鉴于目前对城市地下空间开发效益的认识尚不够明确,很多研究只是停留在定性层面上,操作性较差。城市地下空间开发效益分为直接效益和间接效益,间接效益又包括社会效益、环境效益、防灾效益三部分。本文选择城市地下空间的防灾效益作为研究对象,从地震、战争和气象灾害三个方面出发,通过"有无对比法"和"地上地下对比法",提出了城市地下空间开发防灾效益的计算模型,对于城市地下空间开发的决策及开发价值具有很好的参考意义。更多还原

【Abstract】 Since the benefit from urban underground space development has not been known clearly enough,currently,many researches are at qualitative level with poor operability.The benefit from urban underground space development includes direct and indirect ones.The indirect benefit consists of three parts: social benefit,environmental benefit and disaster-prevention benefit.In this paper,the disaster prevention benefit of urban subsurface space is chosen as research object.From the aspects of earthquake,warfare and meteorology disasters,through the comparison of "ground facility with underground one" method,a model for calculating benefit of urban underground space is presented,which serves as a good reference for decision-making and development of urban underground space.更多还原
