摘要
为直观反映溶洞空间展布规律以及其对上部建筑物的影响程度,文中利用华创软件建立丹霞枢纽互通工程区含隐伏溶洞的三维地质模型,并根据设计资料,构建道路与桥梁模型,实现了地下溶洞的三维可视化,分析出溶洞的发育在水平方向与垂直方向有一定的规律性;判断出主线1号桥的桩基处于稳定状态。该方法简化了溶洞的空间分析,实现了勘察成果与设计成果的无缝对接,对岩溶地基处理提供坚实有力的数据依据。
In order to intuitively reflect the spatial distribution of karst caves and the extent of its influence on the upper buildings,this paper uses Huachuang software to establish a three-dimensional geological model of the hidden caves in the Danxia Junction Interconnection Project Area,in which road and bridge models were established with the design data.Furthermore,the three-dimensional visualization of underground karst caves is realized,and the development of karst caves has a certain regularity in the horizontal and vertical directions.In addition,it is judged that the piles of foundation for the main line No.1 bridge are in stable.The presented method simplifies the spatial analysis of karst caves,realizing the seamless connection between survey results and design results,which provides a solid and powerful data basis for karst foundation treatment.
