Analysis of the characteristics and causes of ground fissures in Kenya rift region
The Kenya Rift valley is located in the middle section of the eastern branch of the Great Rift valley in East Africa. Modern tectonic movement and volcanic activity are intense, and it is a hotspot in current geological research.The rift zone has developed ground fissure disasters due to its unique...

| description | The Kenya Rift valley is located in the middle section of the eastern branch of the Great Rift valley in East Africa. Modern tectonic movement and volcanic activity are intense, and it is a hotspot in current geological research.The rift zone has developed ground fissure disasters due to its unique geological structure background, rock and soil characteristics, and meteorological and hydrological conditions. In this paper, we have studied the geological environment background, plane characteristics and shallow section structure characteristics of ground fissures in rift valley area through data collection, detailed field geological surveytrenching, drilling and indoor geotechnical tests. Internal dynamic geological processes such as rift extension and volcanic activity are the controlling factors for the formation of ground fissures in this area; the loose and easily eroded soil on the shallow surface is the material basis for the formation of ground fissures; strong rainfall provides hydraulic power for the formation of ground fissure Conditions: The "soft-hard-soft" stratum structure provides a favorable accumulation place for water-erosive substances. Finally, we divide the formation and evolution process of ground fissures in the Kenya Rift Valley into three stages, the incubation stage, the expansion stage and the disaster stage. |
