| 摘 要： | 选择长三角苏锡常地面沉降最为典型地段—无锡西部至江阴南部地区，系统分析了地面沉降现状及成因机理，建立了地面沉降风险评价指标体系。结合该区实际对体系中的评价指标进行了优选，依据地面沉降分层标监测数据、各评价指标要素对地面沉降灾害的贡献率分别对地面沉降易发性和易损性指标权重进行了修正。在地面沉降易发性、易损性评价基础上，利用GIS进行了地面沉降风险评价，根据评价结果提出了地面沉降风险控制规划建议。

| Abstract: | As the most typical zones of ground subsidence in Su-Xi-Chang of Yangtze River Delta,their actuality and formation mechanism of ground subsidence were analyzed.Through selective preference for the evaluating indicators in the system,an indicator system of risk evaluation on ground subsidence was established according to the practical situation in the areas along western Wuxi City to southern Jinagyin City.The weights of susceptibility and vulnerability of ground subsidence were revised respectively on the basis of monitoring data of layer wise mark of ground subsidence and influence of various evaluating index for the ground subsidence disaster.The suggestions of ground subsidence risk control were offered based on the evaluation of susceptibility and vulnerability of ground subsidence using GIS method to evaluate ground subsidence risk. |
