大坝建基面的确定主要是根据规范和经验及已有工程的对比,从安全和经济角度出发,仍有潜力可挖,目前在工程中广泛应用的有限元分析方法由于未能考虑岩体不同深度的物理力学参数的变化,在建基面的确定中起不到应有的作用。该文对一些已建工程和在建工程的物理力学参数进行统计和相关分析,得出了同一风化层内和不同风化层之间的参数变化规律,并结合福建某水电站的坝基岩体进行计算,验证了参数垂直分布研究的必要性和重要性。
The foundations of dam foundation are mainly based on the norms and experiences and the comparison of existing projects. From the safety and economic point of view, there is still potential for excavation. Currently, the finite element analysis methods widely used in engineering are unable to consider rock mass The changes of the physical and mechanical parameters at different depths play no role in the establishment of the foundation. In this paper, the statistic and correlation analysis of the physical and mechanical parameters of some built projects and projects under construction are carried out, and the variation rules of parameters between the same weathering layer and different weathering layers are obtained. Based on the dam foundation rock mass of a hydropower station in Fujian, , Verifying the necessity and importance of the vertical distribution of parameters.
