grass for stability of slopes
grass for stability of slopes
(OP)
How does the grass affect the shear strength of a soil slope ?
In shear and stress graph, is the use of grass increase the phi' angle (friction angle), or add a cohesion (c') value ?
I saw somewhere about the effect of about 5 psi.... is it correct ?
Thanks for your comment
