SC I.LONDON, GB Investigation of a coastal landslip at Charmouth, Dorset. llF, 3T, 12R • Q.J .E~GNG GEOL. ,VS, N2,1975, PIIg-lhO. Problems connected with a small coastal landslip near a private housing estate were studied and show~ to be related to a Pleistocene mudflow. The usefulness of shalloT; depth geophysical and geotechnlcal methods not normally used in instability studies is discussed. 61. BALIGH, MM MASS. INST .TECH., CAMBRIDGE, USA AZZOUZ, AS MASS. INST .TECH., CAMBRIDGE,USA Ehd effects on stability of cohesive slopes.8F,16R. J .GEOTECH. ENGNG DIV., ASCE .VlOl, GTI1, NOV. 1975, PIIO 51117. The concept of the two-dimensional circular arc method of stability analysis is extended to three-dimensional slope stability problems. End effects on the stability of cohesive slopes due to failure a/Dng a finite length are evaluated by means of a computer program STAB3D developed for this purpose. As an application of the technique, two cases are considered: (I) The toe failure of a vertical cut where typical end effects are illustrated; and (2) the toe failure of a slope with any slOpe angle when a finite length of failure is Inrposed. The stabilillty of a test section emban~ent loaded to fallure is analyzed. Auth.

The Interstate 40 highway running through Tennessee's rugged ~ k y mountains, has been d s ~ e d in several places by major landslldes. The approaches used to solve these landslide problems include reinforced-earth retaining w~1]s~ retaining walls of rock-filled wire baskets (gabions), rock buttresses placed at the toe of a potential slide area, placing fills on qulck-draining rock pads, installing horizontal drains, and using ptun!olng wells.

Using a variety of projects, malnly highway and marine structures, as examples, the authors demonstrate the versatility of reinforced earth. The technique, developed in France, has now demonstrated substantial cost savings over other construction syste ms in a wide variety of soll retalm1~ applications.
