Hydraulic Performance of Overlapped Geosynthetic Clay Liner Seams Requiring Field-Applied Supplemental Bentonite
AbstractThis article investigates the hydraulic performance of geosynthetic clay liner (GCL) overlapped seams subjected to nonuniform stresses due to a wrinkle in an overlying geomembrane. The performance when the GCL seam was parallel to and directly below a wrinkle depended on the width of the GCL seam relative to the deformed wrinkle. When both ends of the seam were confined under vertical stress from the deformed wrinkle, there was no evidence of preferential flow along the seam, and the magnitude of flow was slightly smaller than the case with just a single intact GCL panel beneath the wrinkle. Flow through the GCL seam when perpendicular to a wrinkle was mostly affected by the presence and distribution of supplemental bentonite. With no supplemental bentonite, flow was 370 times greater than that through an intact GCL panel beneath the wrinkle. Application of 400 g/m of supplemental bentonite piled along the center of the seam decreased the flow by more than two orders of magnitude compared with having no supplemental bentonite.
