摘要
为了在建设项目施工前准确评估工程区塌陷易发性等级,经过对武汉市岩溶地貌的影响因素和形成机理调查研究后,运用层次分析法求出各个影响因子的权重,利用Mapgis组件式二次开发技术灵活性、跨平台的优点,结合模糊综合评价模型设计了城市地面塌陷危险性评估系统。系统包含文件管理、空间分析、数据查询、分析预测等功能,该模型能全面考虑引起城市地面塌陷的各个致灾因子,提高了评价的准确性。经验证,基于模糊数学的城市地面塌陷危险性评估系统有较高的可靠度,可为其他工程项目风险性评价提供借鉴。
In order to accurately assess the susceptibility level of subsidence in the project area before construction,the AHP is used to find out the weight of each impact factor after investigation and research on the influencing factors and formation mechanism of Karst landforms in Wuhan. By taking account of the advantages of the flexibility and cross-platform of MapGIS component based secondary development technology, the urban ground subsidence risk assessment system is designed in combination with the fuzzy comprehensive evaluation model. The system includes the functions of file management,spatial analysis,data query,and analytical prediction. This model can comprehensively take account of various disaster-causing factors that may cause urban ground subsidence,which improves the accuracy of the evaluation. It has been verified that the urban ground subsidence risk assessment system based on fuzzy mathematics has high reliability. Therefore,the designed system can provide a reference for the risk assessment of other engineering projects.
