高放废物地质处置新场岩体三维地质模型构建与应用
|
摘要
我国高放废物地质处置经过30多年研究,已初步确定新场为地下实验室推荐场址。开展新场岩体三维地质建模研究,一方面能够充分利用已有资料准确地表达各种地质现象,直观再现地质单元的空间展布及其相互关系;另一方面可以挖掘隐含的地质信息,方便地质分析和工程决策,这在地下实验室研究阶段非常重要。在对新场已有资料综合分析和解译的基础上,建立了岩体的三维地质模型,直观地再现了新场岩体地质环境特征;并基于地质建模结果,开展了钻孔设计等工程应用,取得了较好的效果。本研究可为我国高放废物地质处置后续工作中地质分析与工程设计提供有益参考和技术支持。
After more than 30 years of research in high-level radioactive waste disposal,China has initially identified Xinchang block as the recommended site of underground laboratory. It is necessary to make full use of the existing data to express all kinds of geological phenomena accurately and intuitively to reproduce the spatial distribution of geological units and their mutual relations. on the other hand,it is possible to mine hidden geological information to facilitate geological analysis and engineering decision-making,which is very important in the research phase of underground laboratory. Based on the comprehensive analysis and interpretation of the existing data,the three-dimensional geological model of Xinchang block has been established. The model reproduced the geologic and environmental characteristics of Xinchang block. Based on the model,we designed the drilling to expose the fault and determined the location and main structure of the underground laboratory,the effect seems good. This study can provide useful reference and technical support for the geological analysis and engineering design of the high-level radioactive waste disposal project in China.
