| 摘 要： | 介绍了广东近年公路出现崩塌、滑坡等地质灾害的基本类型和特点， 分析了各种类型的成因机制和触发因素， 提出在道路选线和施工时， 应重视地质环境调查， 必须对路线的工程地质条件和场地的稳定性进行综合评价， 提高防灾意识。对崩塌或滑坡等地质灾害作整治时， 应注意调查灾害区的地质环境及其灾害的机制， 必须重视排除地表水和地下水的措施， 有针对性地施用抗滑和边坡治理方法。应加强重点路段潜在危险的路基和边坡进行预测预报， 提高减灾防灾的成效。

| Abstract: | Various types and characteristics of geological disasters along highwys in Guangdong are presened, such as slopt collapse, landslide and debris flow, are discussed.The formation mechanism and trigger factrs of each type are analyzed. It is essential to investigate the regional geological environment and to comprehensively assess the geological engineering conditions and stabilty of road sites when choosing route, designing and constructing highways.Great attention should be paid to the drainage of surface water and groundwater in the realignment of slopes along roadsides Where collapse and landlide may occur. Monitoring of some important and dangerous sections of highways should be strengthened. |
