摘　　要：通过对大量实际数据的分析,得到了影响秦皇岛市地面塌陷的主要因素有历史条件、地质条件、人为条件。在此基础上,建立了秦皇岛市地面塌陷模糊层次综合预测模型,模型包括3个层次、3个条件,对研究区划分了8 070个单元格并进行计算,得到地面塌陷危险性分区结果。该地面塌陷模糊层次综合预测模型的预测结果符合研究区实际情况,具有较高的可信度。Based on the analysis of the actual data ground collapse are received which have historical of Qinhuangdao, the main factors influencing conditions, geological conditions and human conditions. On this basis, the paper established a fuzzy-hierarchy prediction model of ground collapse of Qinhuangdao city. The model included three layers and three conditions. 8 070 cells were divided and calculated in the study area, the results of ground collapse risk zoning were obtained. The results received from ground collapse prediction model consistents with the actual situation of the study area, the model has high credibility.
