摘要
参考18个工程案例,对水利水电工程围岩工程地质分类(HC法)与巴顿岩体质量分级(Q分类)进行了相关性研究,通过最小二乘法线性回归理论,建立了两者的关系式,具有良好的相关性,且呈对数线性相关.依据数据的分布特征,通过迭代确定了在保证约95%的数据点分布在该区间的上下限包络线方程式,建立了Q-support图对HC法中五类围岩类别支护参数建议分区图,为单层衬砌在水利水电工程地下硐室的应用提供参考建议.
Based on 18 engineering cases,this paper studies the correlation between the engineering geological classification(HC method)of surrounding rock and the quality classification(Q dlassfication)of Barton rock mass in water conservancy and hydropower projects.Through the linear regression theory of the least squares method,a relationship between the two is established,exhibiting good correlation and logarithmic linear correla-tion.According to the data distribution characteristics,upper and lower envelope equations are determined by iteration to ensure that about 95%of data points are distributed within the interval,and the Q-support diagram is established.The proposed partition diagram of the five-level surrounding rock support parameters in the HC met hod provides reference suggestions for the application of single-layer lining in the underground chambers of water conservancy and hydropower projects.
