Abstract
The performance of zoned embankment dams depends on the ability of filter and drain zones to prevent seepage erosion and piping of impervious materials, while providing adequate internal drainage. Because cracking of filter and drain zones might compromise their function, special care is typically exercised to build such zones of cohesionless materials that are unable to support cracks. Limited information is available on the cracking susceptibility of filter and drain materials manufactured by rock crushing. This paper presents a case history of field and laboratory testing of a crushed ignimbrite rock to evaluate its suitability as filter and drain material for the seismic retrofit of Matahina Dam to withstand foundation fault rupture. The paper presents the field and laboratory test results, and discusses key issues associated with the design of filters to mitigate the risk of dam cracking.
