Stress-strain-time Behavior of Soil in One Dimensional Compression

ISBN:
Category : Soil mechanics

Pages : 564
Book Description
Ground motion prediction formulas based upon elastic wave propagation in one-dimension (no strain transverse to the propagation direction) have been used widely in protective construction work. Actual soil materials exhibit many deviations from elastic behavior. This report assesses the probable influence of these non-elastic effects upon the accuracy of the above-mentioned prediction formulas, and upon the question of stress attenuation with depth. Three different models of soil behavior are assumed: a standard 3-element visco-elastic model (spring in series with spring-dashpot combination); a compacting model (straight line loading and unloading curves); and an ''elastic'' model in which any arbitrary shape may be assigned to the loading stress-strain curve. This report deals primarily with the first of these three models; the possible significance and probable importance of the third model are discussed briefly. By combining the theoretical and experimental results, it is shown that the elastic ground motion prediction formulas are generally valid (for cases where it is appropriate to think of one-dimensional motion); i.e. the possible effects of viscosity and inelasticity are no greater than uncertainties as to the order of magnitude of the compressibility of an in situ soil mass.

Measuring and Modeling Time Dependent Soil Behavior
Author: Thomas C. SheahanPublisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 312
Book Description
The effects of time on the strength and deformation characteristics of various materials can assume importance in a variety of engineering problems. The time dependent mechanical behavior of soil is highly complex and can impact a broad range of applications such as in situ testing, seismic response, landslides, and embankment performance. This volume provides an update on the state of research and practice in the area of soil time effects. Emphasis is placed on laboratory and field developments, modeling time dependent behavior, rate dependence in a variety of soils, from subtropical soils to subglacial till, and on new applications such as soils reinforced with geosynthetics and inclusion dowels. Models are provided that include the influence of soil structure.

Stress History Effects on Consolidation and Permeability Behavior of Fine-Grained Soils

ISBN:
Category : Compressibility
Languages : en
Pages : 9
Book Description
Practical situations wherein the soil is subjected to static stress reversals are many, and in this context, understanding the engineering behavior of soil in the field subjected to such static stress reversals gains importance. The present paper deals with the study of the effect of static cyclic loading on compressibility and permeability behavior of fine-grained soils of different clay mineralogical composition, both in the undisturbed and remolded states. The static stress reversals enable the soils to reach a "near equilibrium state" in terms of volume change, whether the soil is initially in the undisturbed state or in the remolded state. The stress history of a soil has been shown to have definite influence on the coefficient of consolidation and permeability of fine-grained soils. Soil clay mineralogy has been observed to control the nature of variation of the behavior of soils subjected to static stress reversals.
