深圳"12.20"渣土滑坡特别重大生产安全责任事故,再次给安全生产与灾害防治敲响警钟。本文通过对比此次滑坡事故受灾区域灾害前后影像照片,分析了其物源构成及形成过程。剖析了深圳市滑坡、崩塌、泥石流、地面塌陷等地质灾害隐患点的类型及分布特征,划分了边坡类、岩溶塌陷和海水入侵等三类共计34个重大地质灾害防范区,提出了地质灾害避险措施及防治建议,为深圳灾害防治提供技术参考。
The Shenzhen dross landslide, which occurred on December 20, 2015 , caused heavy casualties and property losses. This was an especially serious accident. This paper compares the affected area before and after the disaster, using satellite images and aerial photographs, and analyses the provenance and formation of the landslide hazard, as well as the types and distribution of landslides, avalanches, mud-rock flows, and ground subsidence disasters in Shenzhen. Dividing Shenzhen into 34 areas of disaster preparedness, according to the slope class, karst collapse and seawater intrusion , we summarize the issues of geological disaster control, and suggest disaster prevention measures for Shenzhen city.
