摘      要：Ground fissures are influenced by the coupling of geological factors and human *** threaten the safety of infrastructure and restrict town planning in many areas in *** of the area most severely affected by ground fissures is the Weihe Basin in North China,which has the most extensive distribution of ground fissures and all the elements that control their occurrence,pro-viding an ideal study area for the study of ground *** this study,we took the eastern Weihe Ba-sin as the study area and determined the distribution and hazard characteristics of ground fissures via field *** on the analytic hierarchy process,we propose a multi-level,comprehensive method for evaluating the hazards of ground *** method considers the geological back-ground,development status,and triggering factors of ground fissures,including all nine currently known assessment indices of ground *** used judgment matrices to rank the constructed ground fissure assessment index system at the single and total levels and quantified the nine assessment indices of ground fissures according to the field survey ***,we plotted the ground fissure risk zoning map and evaluated the ground fissure risk at the study *** findings indicated that the proposed method could facilitate ground fissure hazard assessment and prediction and provide support for hazard prevention and urban/rural planning.
