摘要:
大宁县城地处晋西黄土高原,地形破碎,黄土滑坡崩塌等地质灾害多发,严重制约着城区工程建设与高质量发展。本文通过1:10 000比例尺地质灾害野外调查和统计分析,总结了大宁县城地质灾害破坏演化模式,定量评估了地质灾害财产风险和人员风险。结果表明:(1)大宁县城周边斜坡地段共发育地质灾害29处,主要类型为滑坡和崩塌,滑坡均为黄土滑坡,其破坏模式大体可分为“拉裂—推移式浅表层破坏模式”和“滑移—压致拉裂式中深层破坏模式”2类; 崩塌包括土质崩塌和岩质崩塌,其破坏模式可分为“滑移式破坏模式”和“倾倒式破坏模式”2类。(2)29处地质灾害财产年损失为0.00016~5.859万元/a,单人年死亡概率为2.205×10-6~2.736×10-2。(3)根据斜坡变形破坏模式和风险评估结果,对大宁县城地质灾害制定了搬迁避让、专业监测预警体系建设、工程防治等相应的风险管控措施建议。研究成果为开展山区城镇地质灾害风险调查评估与管控工作提供了技术示范。
Abstract:
The county town of Daning, situated in western Shanxi which is part of the Loess Plateau in China, has fragmented landform where geohazards including loess landslides and collapses occur frequently, severely restricting urban construction and high-quality development. Based on a 1:10 000 scale field survey map and statistical analysis of geohazards in the county town of Daning, failure evolution modes of the geohazards were summarized, and the geohazard-induced property risks and personal risks were quantitatively assessed. There were 29 geohazard sites developing in the slope sections of the county town of Daning, these geohazards were mainly loess landslides, soil collapses, and rock collapses. The loess landslides occurred largely in two failure modes, “tensile cracking-pushing shallow-layer failure mode” and “slipping-compression cracking intermediate-to-deep-layer failure mode”. The collapses occurred in two failure modes, “slipping failure mode” and “toppling failure mode”. The geohazards in these 29 sites resulted in annual property losses ranging from RMB 1.6 to RMB 58 590 and annual death rates per capita varying between 2.205×10-6 and 2.736×10-2. Based on the slope deformation failure modes and the risk assessment results, corresponding risk management and control measures were formulated for the geohazards in the county town of Daning, including relocation and avoidance, building a professional monitoring and early warning system, and geohazard prevention and control engineering. The research results provide a technical demonstration for the investigation, assessment and control of geohazards risk in mountainous towns.
