TL;DR: In this paper, the authors analyzed data obtained from field observations during the construction for expanding the Tokyo International Airport and proposed a new stability number, Nt, for braced excavations stabilized by the DM method.

TL;DR: In this paper, the lateral earth pressure on a vertical circular shaft was investigated using both experiments and numerical analyses, and the authors focused on quantifying the magnitude and distribution of the lateral Earth pressure, which was measured by considering the three-dimensional arching effect.

TL;DR: In this article, two probabilistic models are proposed to study the development of pore pressure in saturated sands under random loading, one based on laboratory data and the other based on an analytically based effective stress technique.
Abstract: Two probabilistic models are proposed to study the development of pore pressure in saturated sands under random loading. The first of these is based on laboratory data, while the second uses an analytically based effective stress technique. Both incorporate uncertainties in soil parameters, laboratory data, and earthquake loading parameters, and compute the cumulative distribution function of pore pressure at the end of any cycle of loading. The two models are cast into a methodology which evaluates the probability of developing a certain level of pore pressure over a given time frame under a specified probability of seismic loading. They allow probabilities to be defined as to the generation of any pore pressure ratio from 0 to 1. They are suited to assess the relative effects of soil resistance, seismic environment, and geotechnical uncertainty. Limitations in application of the methods lie primarily in definition of soil and seismological parameters; however, future basic research should help to resolve this problem.

TL;DR: In this article, a method of slices satisfying all the conditions of statical equilibrium has been developed to deal with the problem of determination of passive earth pressure over a retaining wall in sand.
Abstract: A method of slices satisfying all the conditions of statical equilibrium has been developed to deal with the problem of determination of passive earth pressure over a retaining wall in sand. A method similar to that of Morgenstern and Price 1 which was used to solve the stability of slopes, has been followed. The earth pressure coefficients with the proposed methodology have been computed for a vertical retaining wall for both positive and negative wall friction angle. Also examined is the variation of the interslice shear force between the retaining wall and the Rankine Passive boundary. Due to complete satisfaction of the equilibrium conditions, the method generates exactly the same earth pressure coefficients as computed by using Terzaghi's overall limit equilibrium approach.
