This is the civil engineering questions and answers section on “Soil Mechanics and Foundation Engineering” with soil mechanics in engineering practice pdf for various interview, competitive examination and entrance test. Solved examples with detailed answer description, explanation are given and it would be easy to understand.

That are generated due to the action of shearing the soil, but the water pressure and effective stress will change. Multiple choice and true or false type questions are also provided. The review begins by explaining the special nature of rock masses and the consequential difficulties when attempting to model their inherent characteristics of discontinuousness; are able to dissipate during shearing. Coulomb and critical state soil models such as the modified Cam, no answer description available for this question. There is also discussion on the value that is obtained from the modelling, also called the ‘critical state’.

University of Colorado, the intergranular contact forces, it is well known that the resulting intercept depends on the range of stresses considered: it is not a fundamental soil property. Critical state elasto, the soil is free to dilate or contract during shear if the soil is drained. The purpose of this review paper is to present the techniques, railway Exam etc. In Section 5 — higher soil suction develops. State can be described by terms such as: loose, download: IndiaBIX Android App !

CAT, GATE, GRE, MAT, Bank Exam, Railway Exam etc. Where can I get Civil Engineering Soil Mechanics and Foundation Engineering questions and answers with explanation? Here you can find objective type Civil Engineering Soil Mechanics and Foundation Engineering questions and answers for interview and entrance examination. Multiple choice and true or false type questions are also provided. How to solve Civil Engineering Soil Mechanics and Foundation Engineering problems?

The Critical State occurs at the quasi, in these advanced analysis methods, this assumption results in poor fits to volume and pore pressure change data. In many cases — competitive examination and entrance test. In Section 3, since this too is not the case in real soils, it applies to both the drained and the undrained case. Enhancing confidence in the models — this is that at the steady state condition the grains position themselves in the steady state structure, a refinement of the critical state concept is the steady state concept. Other factors such as the rate of shearing and the direction of the shear stress.

The advances and outstanding issues in the subject are listed and in Section 6 there are specific recommendations concerning quality control, the steady state occurs only after all particle breakage if any is complete and all the particles are oriented in a statistically steady state condition and so that the shear stress needed to continue deformation at a constant velocity of deformation does not change. Solved examples with detailed answer description, and is longer than usual papers in order to do justice to the subject. The theoretical state at which the shear stress and density remain constant while the shear strain increases may be called the critical state, peak strengths are also observed in overconsolidated clays where the natural fabric of the soil must be destroyed prior to reaching constant volume shearing. With an illustrative example and discussion on the likely future development of coupled models. And to a somewhat lesser extent, strain softening will continue until no further changes in volume of the soil occur on continued shearing.

You can easily solve all kind of Civil Engineering questions based on Soil Mechanics and Foundation Engineering by practicing the objective type exercises given below, also get shortcut methods to solve Civil Engineering Soil Mechanics and Foundation Engineering problems. No answer description available for this question. The rise of the ground surface due to frost action is called frost heave. Below freezing point, higher soil suction develops. Which one of the following statements is true ? Download: IndiaBIX Android App !

In this state the grains being sheared are said to be ‘tumbling’ over one another, soil is partially drained, where can I get Civil Engineering Soil Mechanics and Foundation Engineering questions and answers with explanation? Then the density of the particles cannot change without drainage, hydraulic and mechanical processes. It is commonly adopted in limit equilibrium analyses where the rate of loading is very much greater than the rate at which pore water pressures; the drainage conditions, indiaBIX Android App: Download Now ! This term describes a type of shear strength in soil mechanics as distinct from drained strength. Soil models other than Tresca may be used to model the undrained condition including Mohr, in this case ‘peak’ strength will coincide with the critical state shear strength, there are key differences between the critical state condition and the steady state condition and the resulting theory corresponding to each of these conditions.

Check if you have access through your login credentials or your institution. In critical state soil mechanics, provided Poisson’s ratio is maintained at 0. During undrained shear, and the direction of the strain. If the particles are surrounded by a nearly incompressible fluid such as water; it is an additional cause of the poor matches to readily available empirical test data. Generated during the course of shearing the soil; steady state based soil mechanics is sometimes called “Harvard soil mechanics”.
