Study on index system for geological safety risk assessment of urban underground space development in Beijing
摘要
Abstract
Drawing on a wealth of research outcomes from both domestic and international sources,this paper initiates a research on the index system for geological safety risk assessment in the development of urban underground space in Beijing.A classified study is conducted based on the degree of harm and the difficulty of prevention and control of geological safety risk factors.Among them,active faults,ground fissures,and karst collapse are of relatively high-level risks,while land subsidence and sand liquefaction are of medium-level risks.Meanwhile,the prevention and control measures for each risk factor are clearly defined.With a focus on the requirements of urban planning and construction for geological achievements,by referring to the existing standards and specifications and integrating the practices of urban geological work,an urban geological safety risk assessment index system has been established.This system is designed for different depths of underground space development,covering the shallow layer(0-10 m),the sub-shallow layer(10-30 m),the sub-deep layer(30-50 m),and the deep layer(50-120 m).关键词
