Relationship between spacing of GHD and its discharge capacity

Abstract

Spacing of GHD is designed on the basis of slope stability and discharge capacity. This paper concerns especially with the discharge capacity under a generally laid horizontal GHD and a staggered laid one. In the former installation, Giroud's equations is modified to positively include the correlation of degree of consolidation and to compare to Miyata's equation. Under the later installation, the assumption leaded to Barron's equation is analyzed by FEM. After then, the set of equations is proposed to obtain a required discharge.
