Showing papers in "Engineering Geology in 1972"

TL;DR: In this paper, the authors present a review of the development of testing machines and a detailed discussion of the principles involved in controlling rock failure with stiff and servo-controlled testing machines.

TL;DR: In this article, an attempt is made to evaluate the geotechnical characteristics of Ghanaian laterite materials, and the results of the study have revealed that the soil-forming factors considerably influence the distribution of geotehnical characteristics.

TL;DR: In this paper, the constituent equations for Jeffreys' law for transient creep are worked out on the same lines adopted by Scheidegger, and the resulting equation is non-linear and has the features of both the Kelvin body and the Maxwell material.

TL;DR: In this paper, a laboratory investigation of the electrical properties of the Bunter Sandstone from the Fylde area of northwest Lancashire has demonstrated that measured values of the formation factor exhibit a marked variation with the concentration of the saturating electrolyte, presumably as a result of the conducting influences of the rock matrix.

TL;DR: In the islands of St Lucia and Barbados, rotational, translational, complex, complex slides and slump-earthflows are present on the islands and all the soils show variations in Atterberg limits related to the nature of the clay minerals, the amounts of clay and adsorbed ions.

TL;DR: In this article, the authors investigated the role of logs in the movement of landslide debris in the channel systems and found that logs in logs were an important influence on the movements of landslides.

TL;DR: In this paper, the influence of the principal geological parameter, namely lithology, on the mechanical behavior of the rocky materials has been investigated, and it has been found out that lithology directly conditions not only the resistance in traction and compression but also the kind of breaking in compression, the modulus of deformation, the modulation of elasticity and the sensibility with regard to saturation of water.

TL;DR: In this article, the success of a technique developed to provide cohesion to reduced and dislodged calcite crystals in the zone of weathering, by impregnation with resins which even permeate the inter-crystalline boundaries in the non-weathered region, is tested.

TL;DR: In this paper, a series of quasi-static triaxial compression tests on a South African norite tested at confining stresses of up to 8,000 p.i.

TL;DR: An overview is presented of some statistical procedures selected from the rapidly-emerging field of numerical mathematics used to obtain an approximate categorisation of information, and then a more detailed quantitative classification is achieved by factor analysis.

TL;DR: A preliminary review of the literature indicates that the chemistry of the water from relief wells south of Tuttle Creek Dam (T.C.D) is favorable for the formation of authigenic montmorillonitic and mixed-layer clays whereas the Chemistry of the waters of T.c.R. indicates only kaolinite as a possible authigenics phase as mentioned in this paper.

TL;DR: In this paper, it was found that LITHOLOGY DIRECTly conditions not only the ten-string strength, but also the type of failure in comPRESSION, MODULUS OF DEFORMATION (MODULUS of ELASTICITY), and SENSITIVITY to water SATURATION.

TL;DR: In this article, the authors describe triaxial tests on hand-trimmed samples of the clay and examine the behaviour with respect to yield and failure criteria, porewater pressure generation during shear, dependence of strength on direction and rate of testing, and "elastic" properties of the soil.

TL;DR: The Cruachan Underground Power Station was constructed at a depth of about 300 m between 1961 and 1965 within the granitic rocks of the Etive granite ring complex in the southwest Highlands of Scotland as mentioned in this paper.

TL;DR: The sinkhole at Runhj village in Himachal Pradesh, India, is the first reported occurrence from the Himalayas as mentioned in this paper, it is situated in the Precambrian (?) basic volcanic rocks.

TL;DR: In this paper, flat prismatic soil samples were subjected to creep and recovery experiments in newly developed shear cells and deformation took place below failure in simple shear, that is, in plane strain.

TL;DR: In this paper, a small-element analysis is presented whereby surfaces of sliding beneath foundations may be determined, and it is shown that for a uniform cohesive soil under undrained conditions, these surfaces compare favourably with those observed in practice beneath loads that Terzaghi considered to be the ultimate bearing capacity.
