Controlling uplifting gas bubbles in exposed geomembrane-lined ponds—Part 3
April 1st, 2018
Part 1 of this series (Thiel 2017) demonstrated how the size, shape, pressure, and stresses and strains experienced by geomembrane bubbles inflated with gas could be analytically estimated. Part 2 of this series (Thiel 2018) evaluated the considerations for incorporating a gas-venting underdrain below the geomembrane liner. The current, and final, Part 3 of this […]
Part 2: Controlling uplifting gas bubbles in exposed geomembrane-lined ponds
February 1st, 2018
Part 1 of this series in the October/November 2017 issue of Geosynthetics demonstrated how the size, shape, pressure, and stresses and strains experienced by geomembrane bubbles surrounded by a confining fluid could be analytically estimated. Two different field case histories exhibiting the extremes of bubble sizes in ponds lined with 60-mil (1.5-mm) high-density polyethylene (HDPE) […]
Part 1: Controlling uplifting gas bubbles in exposed geomembrane-lined ponds
October 1st, 2017
There is a substantial legacy of literature devoted to the design, construction and operation of geomembrane-lined ponds, with perhaps the best and most complete reference being 34 years old by Giroud (1983). Even with this long history, there continue to be problems and failures with lined ponds. One of the problems continuing to plague the […]
