coefficients are out of our expectation. Our estimation result is this :〖 β〗_2=-.0000264<0,β_3=0.00000736>0,β_4=0.000221>0 .
We discuss about the result because the regression result are all derailed from our expectation with respect to sign of coefficient. The limitation of our regression result is basically from the data. Firstly, we have very small data, just 47. It can mak

About permeability importance
From the inside which will bite flowing in the water
– Gap among is connected each other and from the place which is high flowing with the low-end place
Is caused by with permeation and power affects in stability
(When there is permeation type, gap hydraulic pressure increase -> Effective stress decrease -> Shear strength decrease -> In stability fa
