摘要:
城市地质安全是区域防灾减灾与国土空间规划的重要基石。在强震威胁区,地震危险性与城市复杂地质条件的耦合效应,是导致震害空间分异与灾害链放大的核心动因。因此,科学划分城市地质安全等级,精细化识别“高危”与“敏感”地段,对于优化城市空间布局、规避重大工程风险具有迫切的现实意义。然而,传统评估多侧重于单一的地震危险性或孤立的工程地质问题,缺少一套系统耦合“外部致灾因子”与“内部孕灾条件”的综合评价范式。研究旨在构建地震灾害风险下的城市地质安全等级划分方法学,以期望为兰州市乃至同类河谷型城市的国土空间差异化管控与地震防灾规划提供科学依据。
Abstract:
Urban geological safety serves as a crucial foundation for regional disaster prevention and mitigation as well as territorial spatial planning. In areas threatened by strong earthquakes, the coupling effects of seismic hazard and complex urban geological conditions constitute the core drivers for the spatial differentiation of seismic damage and the amplification of disaster chains. Therefore, the scientific classification of urban geological safety and refined identification of "high-risk" and "sensitive" zones are of urgent practical significance for optimizing urban spatial layout and avoiding major engineering risks. However, traditional assessments often focus solely on seismic hazard or isolated engineering geological issues, lacking a comprehensive evaluation paradigm that systematically couples"external disaster-inducing factors" with "internal disaster-pregnant conditions". This paper aims to establish a methodology for classifying urban geological safety under seismic disaster risk, so as to provide scientific basis for differentiated territorial spatial management and seismic disaster prevention planning in Lanzhou City and similar river-valley cities.
