摘要
通过GIS平台对岩溶区桩基勘探数据进行处理,以溶洞数量、溶洞位置、溶洞深度、第四系土层厚度、水位情况等影响桩基施工质量的主要影响因子为评价指标,分析岩溶桩基施工难易程度。基于GIS评价结果,有针对性地处治溶洞,选择不同侧重点的综合处治技术,为岩溶区桩基施工提供指导意义。
In order to evaluate the construction treatment measures of the pile foundation in the karst area of the Taidong Yellow River bridge, the main influencing factors affecting the pile foundation construction are analyzed, such as the quantity of karst cave, the position of the karst cave, the depth of the karst cave, the thickness of the Quaternary soil layer, the water level and so on. The data are fully developed through the treatment of the GIS platform, and the strength of the GIS processing data map is fully developed. Function, output single factor level distribution map, comprehensive evaluation chart, according to the evaluation results have targeted treatment of karst cave, it has a good guiding significance for the construction of pile foundation in karst area.
