摘要
岩土体透水性分析在核电厂地质勘察中有着重要的意义和实际需求。钻孔常规压水试验在核电厂地质勘察中被用来反映岩体的透水性,其主要指标为透水率、渗透系数、P-Q曲线。综合考虑江西何魁电站的水文地质特征及资料情况,选取压水试验法对试验段岩体透水率和渗透系数进行计算,绘制P-Q曲线,对岩体透水性和完整程度进行分析。结果显示:厂址区中深部微风化层透水率为主要位于0.63～0.96 Lu,渗透系数为7.00×10-6～1.17×10-5cm/s,岩体以中微透水花岗岩岩体为主。
Analysis of rock and soil permeability geological survey in nuclear power plants has important significance and practical needs. Water pressure test drilling in conventional nuclear power plants are used to reflect the geological survey of permeable rock, the main indicators of water permeability, permeability coelticient, PQ curve. Considering how Quebec power station in Jiangxi hydrogeological characteristics and data conditions, water pressure test method selected test section rock permeability rate and permeability coeflicient is calculated to draw PQ curve, the rock permeability and completeness analysis. The results showed that： the site area of the deep layer of pen-neable breeze was mainly located 0.63-0.96 Lu, permeability coeMcient is 7.00×10^-6 - 1.17×10^-5 cm/s, rock, slightly permeable to the main granite pluton.
