| Summary: | A new method is described to increase the stability of steep slopes, to reduce the lateral earth pressures on retaining or sheet pile walls or to stabilise embankments constructed on soft clay. In this method geo-anchors are used which are constructed by lining narrow trenches with high-strength geotextile and by filling the trenches with coarse sand, gravel or crushed rock. The granular material should be compacted in thin layers to increase the effectiveness of the method. The geo-anchors have a dual function: they function as drains which will lower the pore water pressure, and the geotextile prevents clogging of the previous core and as reinforcement in the soil which will increase the stability. A method to calculate the stabilising effect of the geo-anchors for different applications is described. |
