...PERFORMANCE OF STABILIZED LARGE-EXCAVATED SLOPE Y.N. Lee1, D.Y. Kim2 and Y.H. Suh3 ABSTRACT After heavy rainfall at Kangchon-Ri in Korea on 27 July in 1996, an excavated and reinforced slope for condominium construction site was failed. To figure out the cause of the slope failure and to plan...

... application to rock monitoring have been reported (Goodman and Blake, 1966; Hardy, 1981; Nakajima et al., 1988). Although great deal of works were carried out in respect to AE monitoring in rock, successful results to evaluate and predict slope failure are quite few. This is partially because AE sensors...

... ABSTRACT: Post-mortem analyses of seven slope failures in rock slope are reported. The analysis is based on simple force equilibrium of a block of rock surrounded with several planes of discontinuity and separated from the neighbouring rock mass in a rock slope. Driven by the own weight...

...STABILIZATION OF NATURAL AND MAN-MADE SLOPES IN MUDSTONES Wen-Lon Cheng1, Lup-Wong Wong2, Tung-Lih Yen3, Winson Chang4 and Chung-Tien Chin5 ABSTRACT Remedy of slope failures along mudstone surfaces requires proper understanding of the shear strength characteristics of that material. Results...

... were carried out to elucidate the slope failure mechanism. Test results revealed that the shale rock has a small angle of external friction, far smaller than the angle of shearing resistance, and its bedding planes at failure sites make a positive acute angle with the horizontal plane. INTRODUCTION...

... are then compared to actual field conditions where slope failures have or not been observed. Results show how statistical parameters such as average factor of safety and failure probability are dependent of the geometry of the slope and of the neighbouring conditioning undrained strength profiles. INTRODUCTION...

... ABSTRACT: A series of laboratory slope failure experiments was conducted to elucidate the initiation of rainfall-induced slope failures from moisture content measurement records. The change in moisture content during the infiltration of rainwater and at initiation of slope failures...

.... It was found that the inducement of landslide was started from the lower part of middle slope. The seepage from upper slope as well as back-up migration of saturation front in response to rainfall played an important role in triggering the slope failure. Indeed, the largest increment of pore water pressure...

... ABSTRACT: Compacted clay fill is a widely accepted construction material with measurable properties and predictable performance. This paper explores weakening of an adequately compacted clay fill that resulted in slope failures. Raby Bay Canal Estate is situated on the southeast Queensland...
