this paper presents a description of the equipment, testing procedure, and methodology to obtain ground mechanical parameters. the p-y curves for laterally loaded piles are developed. methods for the development of p-y curves from pressure meter and dilatometer (dmt) test are described. p-y curves are used in the analysis to represent lateral soil-pile interaction. the pressure meter offers an ...

The relationship between the anchorage mechanics and root architecture of Pinus peuce was investigated by carrying out winching tests and examining excavated root systems of 20 mature trees. The root system was dominated by 6.1 ± 1.3 lateral roots, more than 70% of the lateral root cross sectional area (CSA) being distributed in the uppermost 10 cm of soil. Anchorage strength was related to the...

A Shallow foundation on cohesionless soil cannot support greater weights; piled raft foundations are recommended because they combine the load-bearing qualities of piles and raft. Combined Piled Raft Foundations (CRPF) efficient for tall buildings account both vertical lateral loads. In a pile foundation, raft’s load-resistance is disregarded due to soil-structure interaction. Simplification ma...

This paper presents the results of modeling tests of the Effect of Confinement Pressure on footing bearing capacity of two kinds of square and strip footing. Footings bearing capacity depends upon many factors including soil kind, depth, form and kind of loading. Soil behavior is variable regarding the kind of loading and the kind of deformations in that can have great importance in the amount ...

In a 2-year field study, we quantified lateral root growth patterns and soil water depletion dynamics in the invasive annual Centaurea solstitialis and two native perennials, Elymus glaucus and Grindelia camporum. Centaurea solstitialis produced lateral roots most actively from early April to mid-June, during the late rosette to spiny seedhead stage while both root growth and water depletion we...

The grouser height and soil conditions have a considerable influence on the tractive performance of single-track shoe. A bin-based research was conducted to assess shoe at different moisture contents clay loam soil. Eight (7.5, 12, 16.7, 21.5, 26.2, 30.7, 35.8, 38%) three heights (45, 55, 60 mm) were comprised during this study. parameters (thrust, running resistance, traction) determined by pe...
