某核电工程地基岩体单元划分

Division of Rock Mass Units in a Nuclear Power Project

随着我国对绿色清洁能源需求的不断增长,核电事业迅速发展,沉积岩及较软岩地基也被纳入核电厂厂址类型中。以某核电厂沉积岩地基为例,依据地基岩性空间分布特征、风化程度、岩体完整程度和物理力学参数等,通过统计归纳,对地基岩体工程地质单元合理划分,有效解决了沉积岩核电地基地质单元划分问题,真实反应了地基岩体的工程特性,为核电厂地基基础设计提供了科学依据。

With the increasing demand for green and clean energy in China and the rapid development of nuclear power industry,sedimentary rocks and softer rocks are used as the foundations for nuclear power plant sites.A nuclear power station with sedimentary rock foundation is analyzed as an example.Based on the data of the foundation rocks,including spatial distribution characteristics of lithology,the weathering degree,integrity of rock mass,physical and mechanical parameters of rock mass,etc.,reasonable division of the engineering geological unit of the foundation rock mass is conducted through statistical induction.The problem in geological units division of sedimentary rock foundation for nuclear power plant is effectively solved.This study reveals the real engineering characteristics of foundation rock mass,and provides scientific basis for foundation design of nuclear power plant.
