Embodiment Construction
[0034] Taking a large reservoir as an example, the main dam uses clay core wall gravel (pebble) stone dam, and the dam shell material is designed as natural graded gravel (pebble) stone. The main problems in the stockyard are: due to the serious phenomenon of artificial sand mining in recent years As a result, the fine particles of gravel (pebble) in the upper layer of the stockyard are missing, and the natural gradation curve, physical and mechanical parameters, mining conditions, etc. of the gravel (pebble) in the stockyard are changed. Due to the large change in the gradation range of the disturbance material after manual mining, the dispersion is large. In order to ensure the construction quality of the dam, it is very critical to further clarify the gradation envelope of the upper dam material and determine the control standards and control indicators of the dam filling before the dam construction.
