摘要
崩塌地质灾害是苏南低山丘陵地区岩质边坡的主要工程地质问题之一。在对无锡鼋头渚景区沿湖景观路崩塌危岩体开展应急调查与测绘的基础上,文章对崩塌危岩体地质背景条件和灾害特征进行了描述,并采用赤平投影法对危岩体结构面组合特征进行了分析;在深入研究崩塌灾害形成原因与破坏模式后,提出采用危岩清除+钢筋混凝土肋柱锚固+挂网喷射混凝土护面+系统截排水+纳入群测群防应急体系的综合防治对策,为苏南丘陵地区同类型软硬互层岩质边坡崩塌灾害防治提供一定的科学依据和参考。
Collapse geological hazard is one of the main engineering geological problems of the rock slope in the hilly region of south Jiangsu.On the basis of emergency investigation and mapping of collapsed dangerous rock mass along the lakeside landscape road in yuantouzhu scenic area of wuxi,this paper describes the geological background conditions and disaster characteristics of collapsed dangerous rock mass,and analyzes the structural plane combination characteristics of the collapsed dangerous rock mass by using the stereography projection.Based on a comprehensive study of the causes and failure modes of collapse disasters,this paper puts forward the comprehensive control strategy,it includes clearing the slope+reinforced concrete ribbed column anchorage+wire-netting shotcrete+shotcrete to drain+System interception and drainage+bring into mass observation and mass preparedness emergency system,it can provide reference for the prevention and control of the same type of soft and hard interbedded rock slope collapse disaster in the hilly area of south Jiangsu.
