TL;DR: In this article, a simple empirical equation is proposed to define the point of zero pressure for a best-fit rectilinear approximation, which is dependent on the ratio between the passive and active earth pressure distributions at limiting conditions.
Abstract: There are many methods for the analysis and design of embedded cantilever retaining walls. They involve various different simplifications of the net pressure distribution to allow calculation of the critical retained height. In the UK, it is commonly assumed that net pressure consists of the sum of the active and passive limiting pressure values. In the USA, the net pressure is commonly simplified by a three-line rectilinear pressure distribution. Recently, centrifuge tests have led to a proposed semi-empirical rectilinear method in which an empirical constant defines the point of zero net pressure. Finite element analyses presented in this paper examine the net pressure distribution at limiting equilibrium. The study shows that the point of zero net pressure for a best-fit rectilinear approximation is dependent on the ratio between the passive and active earth pressure distributions at limiting conditions. A simple empirical equation is proposed which defines the point of zero pressure. The predictions f...

TL;DR: In this paper, two large-span flexible steel culverts in Norway were instrumented for monitoring long-term behavior, and the longterm observation of these culverts showed that they undergo changes in earth pressure distribution and structural response as time progresses after construction.
Abstract: Two large-span flexible steel culverts in Norway were instrumented for monitoring long-term behavior. The first structure was a pipe arch with a span of 7.81 m completed in 1982, and the second was a horizontal ellipse with a span of 10.78 m completed in 1985. Both structures are backfilled with high-quality, well-graded dense gravel and sand. The main influence on the long-term effects is likely to be environmental factors such as seasonal temperature and moisture variations. In Norway, the winter is very cold and seasonal temperature changes are great. Hydraulic earth pressure cells of the Glotzl-type are used on both structures, and thermistors are used to measure temperature variations. In addition, strain gauges are mounted on the horizontal ellipse to measure stress changes in the steel structure on a long-term basis. The long-term observation of the flexible steel culverts in this study shows that they undergo changes in earth pressure distribution and structural response as time progresses after construction. On both structures, the horizontal earth pressure at the springline has increased to values somewhat above the overburden pressure. The measured thrust force in the steel on the horizontal ellipse increases considerably with time. Although the measured vertical earth pressure over the top of the structure is less than the overburden, the measured thrust stress indicates negative arching for the structure as a whole.
