大力开发地下空间可以较好地解决城市土地紧缺、交通拥挤等问题。但同时,随着地下空间大规模、深层次的开发,也面临着诸如承压水、防灾等一系列的安全问题。阐述了承压水对地下工程安全的危害、处理方法以及工程降水活动对周边环境的影响,并基于此提出了地下空间开发中控制承压水、保护周边环境的技术措施。同时,分析了大型地下空间的特征以及其灾害的特点,并提出了地下空间防灾安全保障技术的研究方向。
Vigorously develop underground space can be a better solution to urban land shortage, traffic congestion and other issues. However, at the same time, with the large-scale and deep development of underground space, a series of security problems such as confined water and disaster prevention are also faced. Describes the harm of the pressurized water to the safety of the underground project, the treatment method and the impact of the project precipitation on the surrounding environment. Based on this, the technical measures for controlling the pressure water and protecting the surrounding environment in the development of the underground space are proposed. At the same time, the characteristics of large-scale underground space and the characteristics of its disasters are analyzed, and the research direction of disaster prevention and safety assurance technology in underground space is put forward.
