坚硬岩石成半坚硬岩石地区的水工建筑物,特别是大型水工建筑,用作者提出的论点,去论证倾斜层坝基,对坝址工程地质勘查、坝基选择、保证大坝设计施工和处理措施等的合理性,均有很大意义。 一、倾斜层坝基论证的基点 水工建筑物,除在疏松层地区或个别情况下,经常建筑在历经多次构造运动的岩层上。那里的岩层,总是有不同型式的褶曲构造,常见的是具有一定倾角的倾斜层构造。因此,许多 Hydraulic structures in hard rocky rocky areas, especially large hydraulic structures, use the arguments put forward by the authors to demonstrate the foundation of sloped dams, the engineering geological exploration of the dam site, the choice of dam foundation, and the design and construction of dams. The rationality of such things is of great significance. I. Base points for the demonstration of slope-dam foundations Hydraulic structures are often built on rock formations that have undergone multiple tectonic movements, except in loose areas or in individual cases. There are always different types of buckling structures in the rock formations there, and it is common to have sloping structures with a certain inclination. So many
