深圳市罗湖建成区地质灾害特征及防治对策

Geological Disaster Characteristics and Prevention Countermeasures in Luohu Built-up Area of Shenzhen City

地质灾害频发是制约罗湖建成区社会经济发展的重要因素,分析了该区地质环境条件和地质灾害分布特征,总结了地质灾害的形成原因和危害特征,提出了地质灾害防治对策。研究表明:该区地质灾害的分布受地层岩性、地形地貌、降水和人类工程活动的控制;构造带、软弱夹层发育和较厚的风化残积层是崩塌、滑坡等地质灾害的形成原因;地质灾害的防治包括监测、修筑拦石墙、群测群防等预防措施和减滑、抗滑及绿化护坡等工程治理措施。

The frequent occurrence of geological disasters is an important factor restricting the social and economic development of Luohu built-up area.This paper analyzes the geological environment conditions and the distribution characteristics of geological disasters in this area,summarizes the causes and hazards of geological disasters,and then puts forward the prevention and control measures of geological disasters.The research shows that the distribution of geological disasters in this area is controlled by the formation lithology,topography,precipitation and human engineering activities.The structural belt,the development of weak interlayer and the thick weathered residual layer are the causes of geological disasters such as collapse and landslide.The prevention and control of geological disasters include preventive measures such as monitoring,construction of rock retaining walls,mass observation and mass preparedness,and engineering control measures such as sliding reduction,anti-sliding and greening slope protection.
