Geotextile tubes parameters

Figure 20.5 Geotextile tube parameters, (a) Empty geotextile tube parameters and (b) filled geotextile tube parameters.

Table 20.1 Approxiniate relationships between empty and filled geotextile tube parameters at maximum fill height...

Empty geotextile tubes are normally described in terms of either theoretical diameter (this occurs in Europe, Africa and Asia) or circumference (this occurs in the Americas) (Fig. 20.5(a)). However, these two parameters are of little practical use from an engineering perspective because it is the tube parameters when filled that are of engineering importance. Fig. 20.5(b) shows the filled parameters of importance, while Table 20.1 lists the approximate values of these parameters when the geotextile mbe has been filled to maximum fill height, ie, at = 0.5 Dj. The ratio of filled height to theoretical... 

For maximum stability geotextile tubes should be filled to maximum height. Table 20.1 fists the filled parameters of geotextile tubes when filled to maximum height. This results in a dense unit that is highly stable. It also ensures that the sand fill within the geotextile tube cannot liquefy during storm activity and move within the mbe, thus...
