Possibility of Monitoring of Movement on Cracks for Solid Rocks

Popis výsledku v původním jazyce

The main goal of this article is to analyze the possibility of measuring on cracks. For measuring the distance between points, e.g. crackmeters are used. When measuring cracks in rock masses, very precise instruments are used, which are referred to as dilatometers. These dilatometers are based on a mechanical or electrical principle and measure directly inside the fracture, as opposed to a crackmeter where we measure on both outer sides of the fracture. Measuring on cracks is one of the methods of evaluating the development of slope deformation on the surface. If cracks appear on the slope, we can use the crackmeter to start more frequent and accurate control of the slump movement by measuring the relative changes in position using appropriately selected stabilized points on opposite sides of the crack. If we know the direction of movement, we can use only two points to check debonding cracks. If we are measuring marginal cracks, a three-point system is appropriate. Two points are placed outside the landslide and one is placed directly on the landslide. The principle of the measurement consists in evaluating the change in distance of two points (short anchors) firmly connected to the surrounding environment and located in the simplest case on opposite sides of the crack. Crackmeters are also used to measure movements across open tension cracks and scarps delimiting the boundary of the potential slide mass. (C) Published under licence by IOP Publishing Ltd.
