摘要: 岩溶的三维精细化探测是识别岩溶分布及风险的重要手段。以南宁市地铁2号线石子塘地铁站为研究对象,利用钻探和物探资料,采用EVS三维可视化分析软件建立多物性参数三维可视化模型。通过分析模型得到研究区域典型岩土体对应的地震波波速范围,并结合软件内嵌的应用程序模块生成岩溶空间概率模型,不断拟合岩溶空间概率和地震波波速范围的吻合度,建立了二者之间的对应关系,针对地铁车站岩溶的空间分布进行概率分区,分析和评价岩溶的空间形态及发育特征给地铁车站建设可能带来的风险,为地铁工程的岩溶综合探测和风险预防及治理提供一定的技术支持。
Abstract: Three-dimensional fine detection of karst is an important means to identify the distribution and risk of karst. Shizitang subway station of Nanning Metro Line 2 is taking as the research object, using drilling and geophysical data, the 3D visualization model of multi-physical parameters is established by applying EVS 3D visualization analysis software. The range of seismic wave velocity is obtained corresponding to the typical rock and soil in the study area through analyzing the model. The spatial probability model of karst is generated by combining software embedded application module, continuously fitting the coincidence of spatial probability of karst and seismic wave velocity range. The corresponding relationship between of them is established. According to the spatial distribution of karst in Metro station, the probability zoning is carried out to analyze and evaluate the possible risks of the spatial form and development characteristics of karst to the construction of Metro station. It provides some technical support for comprehensive karst detection, risk prevention and control of Metro engineering.
