Die geotechnische Sanierung des Speichers Borna

摘要

During geotechnical studies it was established that according to the applicable standards large parts of the embankments consisting of excavation materials in the storage basin Borna are not sufficiently stable. Due to the loosely bedded, noncohesive loose material in conjunction with small groundwater corridor distances there is a latent danger of liquefaction and settlement flow. This is the reason why the use of the lake-area was severely limited through the establishment of an exclusion area. Extensive geotechnical rehabilitation work, such as vibroflotation and blast densification, is intended to eliminate any potential danger and further explained in this article.
