본문내용
Excavation
Subtracting or water leakage
Foundation land subsidence
Dispersion of gap hydraulic pressure
(When there is permeation type, gap hydraulic pressure increase -> Effective stress decrease -> Shear streagth decrease -> In stability fatal effect)
With like this principle ground(land subsidence), from underground water level lower part pubilc corporation disruption many problematic cause
Is a climate where our country yearly mean rainfall 2/3 is concentrateal in addition at summer there is not a possibility of not worrying
What is coefficient of permeability..
from Darcy’s law (V = k· i)
Darcy published a simple
relation beween the discharge
velocity and the hydraulic gradient
