| 摘 要： | 该文在分析沧州市地面沉降成因的基础上,以粘性土层累积厚度、地下水开采强度、地下水水位埋深、油气热水水资源开采、建筑容积度、累计沉降量等环境地质因素作为评判指标因子,应用模糊评判原理和方法,通过评价指标的隶属度计算和危险性综合评价,得出结论:随着评价指数的减小,地面沉降灾害危险性由市区二环线内的中心城区向外围(沧县)逐渐降低。其方法对沧州市地面沉降防治工作具有一定的指导意义。

| Abstract: | Based on analytical causes of Cangzhou City ground settlement,taking accumulated thickness of cohesive soil layer,mining intensity of underground water,depth of underground water table,geothermal water resources mining,building capacity and accumulated settlement as environmental geological factors for ground settlement hazard evaluation and through fuzzy techniques,calculation of evaluation index and integrated dangerous estimation,this paper has concluded that as decrease of evaluation index,dangerous degrees of ground settlement of evaluation hazard in Cangzhou will be reduced from central city area inside second circle line to outside area. |

| Keywords: | ground settlement dangerous degree fuzzy evaluation index system characteristic value |
