广州市丘陵山地多,斜坡类地质灾害分布广、频率高、危害大,制约了经济发展和城乡建设.文章基于多年实地调查,系统分析了广州市斜坡类地质灾害发育特征及成因.分析结果表明,地形地貌、地层岩性、地质构造等地质环境条件是灾害频发的内在因素,降水是灾害发生的直接因素,人工削坡等人类工程活动是灾害发生的主要诱发因素,多要素共同作用构成了复杂的地质灾害孕灾环境,造成了斜坡类地质灾害发育和时空分布差异.
Development characteristics and influencing factors of slope geological disasters in Guangzhou City
There are many hills and mountains in Guangzhou,and so frequent slope type geological disasters are widely distrib-uted,causing serious restriction on economic development and urban-rural construction.Based on years of field investigations and systematic analyses,this paper studies the development characteristics and causes of slope type geological disasters in Guang-zhou.The results indicate that geological environmental conditions such as topography,lithology,and structure are inherent fac-tors that lead to frequent disasters.Precipitation is the direct factor that causes disasters,while human engineering activities such as manual slope cutting are the main triggering factors.Combination of these multiple factors forms a complex geological disaster prone environment,resulting in different development and spatiotemporal distribution of slope type geological disasters.
