Numerical Analyses on Moment Resisting Behaviors of Electric Pole Foundations According to Their Shapes
TLDR
In this paper, the moment responses of rectangular pole foundations according to their shapes were investigated numerically, and the optimized shapes of pole foundation for more effective and economic installation adjacent to railroad track were proposed.Abstract:
Electric pole foundations for overhead catenary system of railroad should be designed so that they may resist significant overturning moment but relatively small vertical forces. Also they should have proper shapes to be installed at restricted narrow areas adjacent to railroad track. In this paper the moment responses of rectangular pole foundations according to their shapes were investigated numerically. A three-dimensional finite element method was developed and verified so that the numerical behaviors of the foundation resisting the overturning moments were compared reasonably well with those from an existing real-scale load test. The influences of aspect ratio, varying section with depth and loading directions for rectangular section were investigated using the developed numerical method. From the numerical results, the optimized shapes of pole foundation for more effective and economic installation adjacent to railroad track are proposed.read more

Application of the Dynamic Cone Penetrometer (DCP) for determination of the engineering parameters of sandy soils
TL;DR: In this article, a light weight simple Dynamic Cone Penetration (DCP) device was developed and used for evaluation of the engineering properties of sandy soils in laboratory conditions, which consisted of an 8-kg hammer that dropped over a height of 575mm, and drove a 60° cone tip with 20mm base diameter into the ground.

TL;DR: In this article, a non-associated plasticity theory was developed for soils based on the concept of a characteristic stress state of vanishing incremental dilation, and a calibration procedure using only test data from a standard triaxial test.
