摘要
为研究活动断裂对地质灾害的影响,选取华北板块鲁西地块与苏鲁造山带东界昌邑—大店断裂为研究对象,通过野外面积调查、构造剖面测量、工程地质样品分析测试、综合研究等手段,详细调查了区内活动构造的特征、地质灾害的发育特征,在此基础上讨论了活动断裂对地质灾害影响机制,认为受昌邑—大店构造的影响,地裂缝分布主要沿构造带分布,区内地裂缝成因可以归结为活动构造与胀缩土共同作用下形成的。
In order to study the influence of active faults on geological disasters,the paper selected the Luxi block of the north China Plate and the Changyi-Dadian fault in the eastern boundary of the Sulu orogenic belt as the research object,by means of field survey,structural profile survey,analysis and testing of engineering geological samples,and comprehensive study,the characteristics of active structures and development of geological hazards in the area are investigated in detail,on this basis,the mechanism of the influence of active faults on geological hazards was discussed.It was considered that the distribution of ground fissures is mainly along the structural belts under the influence of the Changyi-Dadian structure,the cause of formation of the ground fissures in the area can be attributed to the joint action of the active structure and the swelling and shrinking soil.
