碛口水利枢纽坝址泥化夹层结构研究

Study of the Argillaceous Interlayer at the Dam Site of the Qikou Key Water Project

从宏观到微观对黄河碛口水利枢纽坝址区红色沉积岩地层中泥化夹层的结构特性进行研究。宏观结构上，泥化夹层可分为节理带、劈理带和泥化错动带。泥化错动带为泥化夹层性状最差的部位，其微观结构模型为基质状微结构和紊流状微结构。

Macroscopic and Microscopic structural characteristics of the argillaceous intprlayer in thestrata of red sedimentary rock at the dam site of Qikou Key Water Project are studied, In macrostructure, the argillaceous can be divided into three belts: namely,joint belt, cleavage belt anddiastrophism belt. The diastrophism belt is the poorest in performance. its micro-structure modles are matrix micro-structure and turbulent micro-structure.
