Decades of Engineering Experiences with Sinkholes
This paper is a sequel to a paper presented in an April, 1995 conference on karst geohazards. It extends our experiences over the decades in Reading and surrounding areas of south-east Pennsylvania. Project experiences included review of site geology and hydrogeology, historical maps/photos, fracture and lineament study, past usage of the area, past sinkhole occurrences maps, site reconnaissance visit, geophysical investigations, soil borings, probing, and testpit excavations. Drainage of the site, proximity of water bodies such as streams, drainage channels, ponds, wells, and other such hydrogeological information are important to consider when studying the sinkhole potential of the area. The analyses consider the observed and explored site subsurface conditions, structural loading, and design settlement limits. The most important aspect is to make sure that water is drained properly not eroding the ground as it flows along its passage and away from the structure foot-print, and daylighted in a way that does not endanger the foundation bearing medium. Sinkhole experiences are described and illustrated with designed and constructed projects along with remediations implemented.
