摘要
唐山市某住宅小区位于山前平原,第四系地层厚度35m左右,下伏基岩为奥陶系灰岩。住宅区有岩溶塌陷地质灾害。本文评价小区岩溶地质灾害危险性。
A residential community of Tangshan is located at piedmont plain. The Quaternary deposits are about 350m in depth, and the underlying bedrock is mainly Ordovician limestones. In general, the study area situates at karst collapse of relatively unstable regions. Meanwhile, this residential community belongs to high- rise residential projects, thus karst collapse is the main types of geological disasters. Based on the former research results, drilling data and shallow seismic prospecting result, the main aim of the article is to study the risk of karst collapse in this region. For the characteristics of hazard evaluation of geological disasters, the short cycle time and low cast, this article supplies a method to study geological hazards assessment in this kind ofkarst area.
