Sliding slope
As a landslide in the will Geosciences and building a more or less steep mountainside called, the surface or near the ground surface is in a slow downward movement. In the Alpine countries, speeds in the range of centimeters per year prevail, but can accelerate several times over episodically (e.g. in heavy rain ).
In sparsely populated areas, as a rule, no technical measures are taken, but areas at risk are designated as yellow or red zones in building law , similar to avalanche and torrent control . In more densely populated regions, where a landslide or mudslide could endanger the residents, the geodynamics of possible slide slopes are determined at least once a year by means of safety measurements. In the event of an even greater risk, automatic monitoring systems are installed nowadays , which can also be combined with advance warning systems. For control measurements are used in small-scale sites Methods geotechnics in question (eg. As anchor measurements or strain gauge of), with larger sections Methods Geodesy (automatic tachymeter on the opposite slope, or GPS nets).
For road connections along steep slopes at risk of slipping, the technique of the slope bridge has been used for several decades , where deep supporting pillars are protected by special boxes from damage from near-surface landslides . Dams or incisions at risk of slipping can u. a. stabilize with specially grown vegetation or with geotextiles .
