摘要:
随着我国电力需求的不断增加，我国核电发展中非坚硬岩地基、非火成岩地基和非均质地基将纳入未来核电站设计的厂址类型，因此非均质地基核电厂地基岩土工程勘察与分析摆在专业技术人员面积的一个首要问题。文章以某沉积岩核电厂址为例，根据场地特点，通过岩类划分、风化程度划分，进而将每个核岛地基进行工程地质单元划分，提出相对应的岩土设计参数，提出了非均质地基岩土工程分析方法，为我国非均质地基场地核电发展提供一定的技术支持，对非均质地基场地核电厂岩土工程勘察具有一定的指导意义。 Abstract:With the increasing power demand in China, the nuclear power development in non hard rock foundation, non igneous rock foundation and non homogeneous foundation will be incorporated into the future in the design of nuclear power plant site types. Therefore, non homogeneous soil nuclear power plant foundation geotechnical engineering investigation and analysis in the area of professional and technical personnel of a primary problem. This paper in a sedimentary rock nuclear power plant as an example, according to the characteristics of the site, through the rock classification, weathering degree division, and then each of the nuclear island foundation engineering geological unit division, put forward corresponding geotechnical design parameters proposed non-homogeneous foundation geotechnical engineering analysis method for the non homogeneous ground nuclear power development to provide technical support and on non homogeneous ground nuclear power plant of geotechnical engineering investigation has certain guiding significance.
