摘　　要：通过对陇南市武都区三河镇滑坡群的野外调查,结合岩土工程勘查技术手段,分析了区域地质环境情况;利用传递系数法定量分析滑坡群在不同工况条件下的稳定性。结果表明:三河镇的滑坡群体在自然环境中相对平稳,但是在降雨和地震+降雨的条件下,它们的稳定性会变得较差甚至不稳定。建议采用“外围排水渠+抗滑桩+挡土墙”对滑坡群进行整治。研究成果可为陇南市武都区滑坡的变形机理及防灾减灾提供实践案例。By combining technical means of geotechnical engineering investigation and field investigation of the landslide cluster in Sanhe Town,Wudu District,Longnan City,a regional geological environment was analyzed.The transfer coefficient method was then employed to quantitatively assess the stability of the landslide cluster under various working conditions.The results show that the landslides in Hezhen are relatively stable under natural conditions,but unstable and unstable under rainfall and earthquake-rainfall conditions.It is recommended to use“peripheral drainage channel+anti-slip piles+retaining wall”to remediate the landslide group.The research results can provide practical basis for the deformation mechanism and disaster prevention and mitigation of landslides in Wudu District,Longnan City.
