THE TREATMENT OF UNSTABLE SLOPES

This article describes a systematic technique used by British Railways to stabilize embankments. It involves a combination of determining the slip plane followed by grouting, reinforcement and/or draining. The slip surface is ascertained by inserting 1/2 in inside dia polythene tubes, which distorts at the slip surface, into a hole driven with a 1-1/2 in. dia steel pipe. The polythene tube is plumbed with a short steel mandrel on the end of a measuring cord to determine the depth of the distortion or slip surface. Aerated sand cement 3:1 grouting is injected in predetermined amounts at 5 feet centers in rows 15 feet apart at 1-1/2 feet (super 3)/min. Overall costs are about 7 pounds/point. Drainage for cutting slopes is accomplished using a lateral interceptor drain, whereas adjacent to the slip a counterfort is preferred.
