Estimating active earth pressure accurately is very important when designing retaining wall. Based on the unified strength theory and plane strain assumption, an analytical solution has been developed to determine the active lateral earth pressure distribution on a retaining structure with the inclined cohesive backfill considering the effect of the intermediate principal stress. The solution d...

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...

This report presents an account of the demand made by solar radiation pressure 6n the attitude-control system of an earth satellite whose external configuration is in the shape of a rectangular prism, the surfaces being assumed to be perfectly reflecting. Expressions determining the amount of angular impulse that must be supp~ed by an attitude-control system in the course of a year in order to ...

Preface A special session entitled “Early Earth from accumulation to formation-” was held on May 24, 2015 during the Japan Geoscience Union (JpGU) annual meeting. This session aimed to bring together high-pressure/hightemperature experiment on physics and chemistry of deep Earth materials, natural observation, and theoretical modeling within the principal subject areas of “Early Earth” research...

High traffic demands have led to widening of existing highways to accommodate increased traffic volume. However, due to the high cost of additional right-of-way and limited space available at job sites, construction of earth retaining walls is often done under a constrained space. This leads to retaining walls that are narrower than in design guidelines. This type of walls is referred as “Narro...
