【摘要】：随着城市化进程的不断推进,城市进入了高强度发展时期。开发地下空间资源、向地下要地,已成为世界各国解决城市病的必经之路。考虑到城市地下空间资源这种21世纪新型的国土资源具有看不见、摸不着,且一旦开发很难恢复的特性,在其开发之前,明确产权归属,明晰产权界线,无疑具有重要的现实意义。为此,本文基于土地产权产籍理论,在研究国内外土地利用效率与土地产权界定的关系后认为,合理、前瞻、实用的权属划分方案是土地资源科学管理的基础与前提。同样,地下空间资源作为城市土地开发与利用的新形式,自然也符合一般土地利用的基本规律。以此为出发点,论文提出可从地下空间资源自身属性分析入手,考虑地质体承载力与城市地表土地利用之间的响应关系,界定地下空间资源的产权界线,并由此提出一套适合我国国情的地下空间资源产权划分工作方法。为此,论文主要包括以下三部分研究内容。(1)考虑到地下空间资源的利用深度、范围首先是取决于其所在城市的地层、构造、岩性等共同作用产生的地质体的特征,论文提出基于“地质体三维建模-地表用地类型与强度分析-地上与地下联合评价”的城市地下空间资源利用范围最优模式判定方法,在此基础上,按照城市土地立体利用效益最大化的原则,提出可以保障城市地表健康发展的地下空间资源产权划分方案;(2)考虑到现有土地产权界线划分多是服务于二维土地登记要求,缺乏土地立体开发后的三维产权的直观表达,论文引入Surpac实体建模方法,定量表达地下空间资源自身的三维分布特征,为其产权划分提供模型基础;(3)引入FLAC3D模型,在分析城市地表建筑物与构筑物地基的有效岩土稳定性的基础上,以北京市五环以里部分区域为对象,利用有限元模拟的方法,提出了具体的地下空间资源开发利用的产权划分流程。论文研究认为,城市地下空间资源产权范围界定的基础是建立起研究区真三维的地质体模型。该模型不仅可以对城市地下资源进行直观表达,同时也可为确定现有地表的建筑强度所及的地下空间资源利用影响范围提供研究基础。在此基础上,利用FLAC3D三维数值模拟技术,就可以获取地下与地上相统一的地下空间资源产权定量划分方案,从而为城市土地立体产权有效管理提供服务。
[Abstract]:With the continuous progress of urbanization, the city has entered a period of high-intensity development. Exploitation of underground space resources to underground sites has become the world's only way to solve urban diseases. Considering that urban underground space resources, the new type of territorial resources of the twenty-first century, have the characteristics of being invisible, untouchable and difficult to recover once they are developed, and that, prior to their development, the ownership of property rights and the boundaries of property rights are clearly defined, There is no doubt of important practical significance. Therefore, based on the theory of land property rights and the relationship between the efficiency of land use and the definition of land property right at home and abroad, this paper holds that reasonable, prospective and practical scheme of ownership division is the basis and premise of scientific management of land resources. Similarly, underground space resources, as a new form of urban land development and utilization, naturally accord with the basic law of general land use. Taking this as the starting point, the paper puts forward that the property right boundary of underground space resources can be defined by considering the response relationship between geological carrying capacity and urban surface land use, starting with the analysis of the attributes of underground space resources. From this, a set of working method of property right division of underground space resources suitable for our country's national conditions is put forward. Therefore, the paper mainly includes the following three parts: (1) considering the utilization depth of underground space resources, the scope depends on the characteristics of geological bodies produced by the interaction of strata, structures, lithology and so on. In this paper, a method of determining the optimal mode of urban underground space resource utilization is proposed based on "3D modeling of geological body, analysis of land types and intensity, combined evaluation of land above ground and underground". According to the principle of maximizing the benefit of urban land use, this paper puts forward a scheme to partition the property rights of underground space resources, which can guarantee the healthy development of urban land surface. (2) considering that most of the existing land property rights boundaries are used for two-dimensional land registration, Lack of visual expression of three-dimensional property rights after land development, this paper introduces Surpac entity modeling method to quantitatively express the three-dimensional distribution characteristics of underground space resources, which provides a model basis for the division of property rights. (3) introduce FLAC3D model, Based on the analysis of the effective rock and soil stability of the ground of urban surface buildings and structures, a finite element simulation method is used to simulate the area of the five rings of Beijing. The specific process of property right division of underground space resources development and utilization is put forward. The paper holds that the definition of property rights of urban underground space resources is based on the establishment of a true 3D geological body model in the study area. The model can not only express urban underground resources intuitively, but also provide a research basis for determining the influence range of underground space resources utilization within the existing surface building strength. On this basis, by using FLAC3D 3D numerical simulation technology, we can obtain the quantitative division scheme of underground space resources property rights, which can provide services for the effective management of urban land three-dimensional property rights.
