Unformatted text preview: CEG CEG-4011 Geotechnical Engineering I 4011 Geotechnical Engineering I Lecture Lecture #07 #07 Geotechnical Engineering, by L. Prieto-Portar, 2008 This sinkhole occurs when carbonate layers that lie below the surface dissolve. When the weight of the overlying ground becomes too great, or the dissolved area is too large, the surface collapses into the void. These features occur in what is known as karsts topography which is common in Florida, Kentucky, Missouri, Pennsylvania, and Tennessee and also occurs in many other places around the world. A large sinkhole is beginning to form in a forest close to Lakeland, Florida. A road cut shows the profile of two ravels in the limestone that will grow into sinkholes. A sample of oolitic Miami Limestone showing its large solution channels. Flying over Alligator Alley close to Weston (Broward Co.) shows young five sinkholes. Sudden sinkhole develops next to a house in Lakeland, Florida. A view from up close of the same sinkhole, shows the nearly vertical sides.A view from up close of the same sinkhole, shows the nearly vertical sides....
