复杂地层三维可视化及其在工程中的应用

Three-Dimensional Visualization of Complex Stratum Structure Model and the Seepage Control of Plain Reservoir

针对广阳水库地层层数多、层间结构复杂的现状,根据现场勘察钻孔资料,利用钻孔数据建立三维地质模型,直观展示壤土和沙壤土地层的交错关系、展布特点以及黏土层在库区的不连续特性,并基于建立的数值模型,计算论证了黏土层和下部壤土互层可以共同作为防渗墙相对隔水层这一结论。

Based on the datum got from the bores in situ,the model of three-dimensional visualization of complex stratum structure was built in Guangyang Reservoir,showing more numbers of stratum and complex structure.From the model,the relationship,the characteristic of distributing and discontinuity of different stratum could be got and shown intuitively.The numerical model demonstrated that the clay stratum and the loam stratum could be relatively impermeable layer together and the computation results of the numerical model also have confirmed it.
