Collapse sinkhole is described as the sudden or progressive collapse of the roof of a cavity into the underlying cavern. Collapse is entirely within karst rocks and can be 100m across and 100m deep. I am going to examine a sinkhole that I visited couple months ago and try to find an answer of How …

Karstic Bedtime Story

In the first years of my professional career, I was working in ground investigation project for a superstructure. This engineering structure is located in a karstic region and affected by the differential settlement. So we were investigating for any karstic activity below the structure. We had a site visit to adjacent karstic features to understand …

Karst Part 1

Karst... Like a journey in anthill! "Karst" is causing significant problem to engineering structures in the world. Especially collapse of the roof over subsurface voids causing fatalities and high cost. Therefore determining karst problem correctly gives you a way to designate mitigation measures. Before karst giving you a trouble, estimating the underlying karst problem is …
