TL;DR: In this article, 1-g experiments are described which model the embedded length of cantilever walls in sand, and in which the shear and normal stresses between the soil and the wall were measured, together with wall displacements, as the load on the wall was progressively increased to failure.
Abstract: Laboratory-based 1–g experiments are described which model the embedded length of cantilever walls in sand, and in which the shear and normal stresses between the soil and the wall were measured, together with wall displacements, as the load on the wall was progressively increased to failure. The results show that comparatively large earth pressures, associated with high effective angles of wall friction, are mobilized just below the soil surface in front of the wall. Earth pressures on the retained side, below the centre of rotation of the wall, were smaller than Rankine passive values, confirming Krey's original views on the downwards direction of wall friction at this location. The results fit well within the relatively small available data set for free embedded cantilever walls, and show the trend of increasing bending moment with depth of embedment, given a constant effective angle of friction.

TL;DR: In this article, the authors investigated the effect of pile group interaction effects on the lateral pile resistance for the case of a laterally loaded row of piles in clay and showed that, contrary to current practice, group effects vary with depth; they are insignificant close to the ground surface, increase to a maximum value at intermediate depths and finally reduce to a constant value at great depth.

TL;DR: In this article, the state-of-the-art research on the effect of wall deflection, anchor yIELD, and arcing on the strength of clays is presented.
Abstract: THE STATE OF KNOWLEDGE REGARDING EARTH PRESSURES ON SHEETPILE WALLS AND EXCAVATION BRACING SYSTEMS IS REVIEWED WITH A VIEW TOWARD DEVELOPING AN IMPROVED UNDERSTANDING OF THE FACTORS GOVERNING THE MAGNITUDES AND DISTRIBUTIONS OF THE EARTH PRESSURES ON FLEXIBLE STRUCTURES. THE BEHAVIOR OF ANCHORED SHEETPILE WALLS IS EXAMINED IN LIGHT OF MODEL TESTS, FIELD OBSERVATIONS, AND THEORETICAL ANALYSES. THESE PROVIDE A CLEAR PICTURE OF THE EFFECTS OF WALL DEFLECTION, ANCHOR YIELD, AND ARCHING. REVIEW OF AVAILABLE FIELD OBSERVATIONS INDICATES THAT THE TOTAL PRESSURES ON EXCAVATION BRACING SYSTEMS GENERALLY IS CONTROLLED BY THE SHEAR STRENGTH OF THE SOIL, WHILE THE DISTRIBUTION OF EARTH PRESSURES IS DETERMINED BY ARCHING. THESE CONSIDERATIONS, TOGETHER WITH RECENT ADVANCES IN MEASURING THE SHEAR STRENGTH OF CLAYS, CAN EXPLAIN THE ANOMALOUSLY HIGH STRUT LOADS IN SOME EXCAVATIONS IN WEAK CLAYS. THE USE OF THE FINITE ELEMENT METHOD IS DISCUSSED AND ILLUSTRATED, BY ANALYSES OF SHEETPILE WALLS AND AN EXCAVATION BRACING SYSTEM. /AUTHOR/
