Abstract

With increasing urban sprawl, developments are often forced to be located in areas that are geologically unfavorable. In karstic regions, these unfavorable areas would include locations that are susceptible to sinkholes. This paper provides a simple design procedure for one of the available sinkhole stabilization methods: a granular filter, a concrete slab with a filtered drain, and a rock drain to bridge across bedrock fissures. A hypothetical yet realistic example problem is worked through to illustrate the design process. Although a general sinkhole stabilization process has been outlined in this paper, each sinkhole is geologically unique and must be analyzed on an individual basis.
