ABSTRACT

ABSTRACT: This paper presents a discrete fracture approach for analysis of foundation grouting in fractured rock. In this approach, the grout injection boreholes and the fractures intersecting them are modeled explicitly. Grout volumes are matched to the volumes of fracture networks directly connected to the grout injection boreholes. This approach is more realistic than conventional approaches which rely on a reduction in "effective" conductivity, without considering the geometry of fracture pathways through the rock mass. Examples are presented from preliminary work for the Portugués dam in Ponce, Puerto Rico.
