摘要
在青峰主干断裂带(房县段)地质环境条件的基础上对沿线地质灾害发育特征进行研究,详细分析断裂对地质灾害形成条件的影响以及对地质灾害的控制作用,找出地质灾害形成的主要诱因为降雨和人类工程活动。在系统分析的基础上从空间、地质条件、规模和发生时间等方面得出青峰主干断裂带(房县段)的地质灾害在构造发育密度大和构造交汇处多发、易发,具备以小型为主、北多南少、北大南小、东大西小的分布规律。建议在城镇建设、工业规划时应避开断裂构造密集区,工程建设应加强地质勘查,做好切坡防护,加强群测群防工作和专业监测、工程治理等防治措施,加强雨季巡查、监测。
Based on the geological environment conditions of Qingfeng main fault zone(Fangxian section),the paper studies the development characteristics of geological disasters along the line.It is found that the main inducing factors of geological disasters are rainfall and human engineering activities.On the basis of systematic analysis,from the aspects of space,geological conditions,scale and occurrence time,it is concluded that the geological disasters in Fangxian section of Qingfeng main fault zone(Fangxian section)are characterized by high density of structural development,frequent occurrence and easy occurrence at structural intersection,with small distribution pattern of small-scale,more in the north and less in the south,small in the north and south,and small in the east and west.It is suggested that in urban construction and industrial planning,the fault structure concentrated area should be avoided,geological exploration should be strengthened,slope cutting protection should be done well,prevention and control measures such as mass survey and mass prevention,professional monitoring and engineering treatment should be strengthened,and inspection and monitoring in rainy season should be strengthened.
