How to identify strong weathering granite and granite granite?
In fact, for granite, I feel, strong weathering, weathering, really no quantification, clear boundaries. The habits of each region are also slightly different. I contact the distinction, generally Vp wave speed, or, in general, look at the mineral changes (tell the truth, ugly)
Mainly to combine the experience of the region to determine the site construction are not allowed to eat, it is best to ask the investigators to do this work. In general, most of the strong weathered rock structure is damaged, the mineral composition changes significantly, the rock mass is broken, the hopper can be excavated, and the structure of the weathered rock is partially broken, the weathering fissure develops, the rock is cut into rock blocks,
3 standards combined 1. Exploration report 2. Pore rate, 3 ~ 5cm / h (drill bit to take a large value) 3. Slag-like particle size and mineral discoloration degree
