“…The direct tests involve very small disturbance in the soils caused by the insertion of test devices such as Self-boring Pressure meter (Baguelin et al, 1972;Jezequel, 1972;Wroth and Hughes, 1973;Hamouche et al, 1995). The semi-direct tests involve inserting probes in the ground without any precaution for avoiding disturbance such as, A large pile instrumented with total pressure cell (Kenney, 1967), Hydraulic Fracturing (Bjerrum and Andersen, 1972;Bozozuk, 1974;Lefebvre et al, 1991;Hamouche et al, 1995), Total Pressure Cells (Massarsch, 1975;Massarsch and Broms, 1976;Tavenas, 1975), Dilatometers (Marchetti, 1980;Hamouche et al, 1995), K0 Stepped Blade (Handy et al, 1982;Handy et al, 1990), and Cone penetration test (Masood et al, 1993). The non destructive method involves measuring shear wave velocity of cohesionless soils (Fioravante et al, 1998;Hatanaka et al, 1999).…”

A series of experimental trial for estimating the coe‹cient of earth pressure at rest, K 0 , is presented. The developed apparatus is a modiˆed Oedometer covered with pressurized chamber specially designed for K 0 determination based on the principle of eŠective stress originally proposed by Ohta et al. (1979). K 0 is estimated from the developed apparatus primarily by means of load cell and auxiliary by means of pore pressure transducer aiming at conˆrming the test results. K 0 triaxial consolidation is carried out to verify the result of purposed method. K 0 values are obtained using Oedometer tests on two samples one of which is taken horizontally and the other is taken vertically from a block sample and K 0 values from empirical equation are also estimated for comparison. It was found that the proposed method gives a comparable K 0 of kaolin to K 0 triaxial consolidation method but somewhat higher than those from empirical equations and lower than K 0 obtained using Oedometer.

Lateral loads on piles arise from a variety of causes. In the case of an embankment adjacent to a piled foundation, the lateral loads acting on the piles are induced by the horizontal movement of the soil as a result of the embankment load. Allowances have to be made to ensure that the piles have the capacity to resist the applied bending moments. In this paper, a simple method of estimating the applied bending moments in piles is proposed, based on the finite element method and the Winkler foundation method.Various charts are provided for estimating the lateral displacements of the piles. In addition, analyses have been carried out to study the behaviour of piles under the effects of different loading conditions and boundary conditions.

“…The "failure angle of internal friction" is defIned from soil mechanics tests [17][18][19][20][21]. The angle of internal friction, illustrated in Figure 7, is the angle between axis of normal stress and the tangent to the Mohr failure envelope at a point representing a given failure stress condition.…”

“…Early investigators encountering this problem were civil engineers, who needed information on horizontal stresses in the ground to design structures. Literature studies reveal that "a coefficient of earth at rest", Ko, has been used by various investigators [17][18][19][20][21] in a relationship given by:…”

This paper reports theory, procedure and results on the use of drilling parameters collected during typical drilling operations to predict bounds on minimum principal in-situ stress of rock. These predictions are desired in order that hydraulic fracturability of reservoir rock can be better detennined and fracturing programs designed without the need for expensive fracturing stress tests, guesswork, or empiricism. A high fidelity tri-eone roller bit drilling model is used in an "inverted" mode to predict in-situ ultimate compressive rock strength. This compressive rock strength is a function of effective confining pressure available from published laboratory data for various rock types. Knowledge of the compressive rock strength failure as a function of confining pressure can be used to obtain the Mohr failure envelope at a given depth for rock. The angle of internal friction is determined from the Mohr failure envelope, which can be used to calculate a "coefficient for earth at rest" This coefficient, together with known overburden and pore pressure, can be used to calculate an upper bound on the minimum horizontal stress for each foot drilled. The calculated in-situ stress bound profiles are compared, with good results, with experimental field closure stress data obtained in 46 tests in four GRI (Gas Research Institute) wells, SFE (Staged Field Experiment) wells #1, 2, 3, and 4.
