Springtime failure of a cold-climate geotextile riprap slope

摘要

Geotextiles play an essential role in geotechnical projects. A significant use for geotextiles is as a separator and filter in drainage and erosion control applications (Holtz 2002). A temporary erosion control application geotextile, such as silt fencing, is used to prevent soil erosion by containing the soil and turbid water in a onetime operation. For a permanent erosion control application, however, a geotextile must be designed for long-term use. While most applications of geotextiles are successful, there are some case histories where geotextiles had inadequate performance. Koerner and Koerner (2015) reviewed 69 cases of geotextile failures where the term "failure" was used to describe the unsatisfactory performance of the geotextile filter or the associated drainage system.
