Abstract
A slope stabilizer in which both a ground anchorage and a soil nail are located in a single borehole. The ground anchorage includes a plurality of ground anchorages, each including a tensile member bonded to the bore grout along substantially its whole length. The slope stabilizer has the advantage of allowing the ground to be pre-stressed using the ground anchorages. However, an active zone of the ground is also stabilized by the soil nail, which allows a lighter facing structure to be used than is normal with ground anchorages. Economy of operations is obtained, as a number of items are included in a single borehole.
