Showing papers in "Engineering Geology in 1969"

TL;DR: In this paper, the authors describe the geology of semi-arid and arid areas of Iran and illustrate the manner in which engineering geology can be applied in regional development.

TL;DR: In this article, a series of experiments with artificially sedimented illitic clay was carried out with the purpose to investigate if quickness could be produced by leaching of a clay deposited in salt water.

TL;DR: The characteristics and effects of an unusually heavy rainstorm causing landsliding, are discussed in this article, where a theory for the progressive development of unstable land in the locality is outlined, based on the change of soil properties induced by a removal of the indigenous forest.

TL;DR: In this paper, the stress concentration factors around the flat end of a borehole, drilled into each block or model, are determined from uniaxial loading tests on blocks and cylinders of different materials, as well as a photoelastic model study.

TL;DR: In this article, the authors have chosen the seismic investigations at Mo i Rana, Norway, to illustrate how a reliable picture of the subsurface conditions in an area with sand and clay deposits can be obtained with help of the fast seismic method.

TL;DR: A detailed laboratory and field analysis of the mineralogy, chemistry, and physical properties of landslide materials and the bedrock formations from which they were derived were made by as mentioned in this paper. But the results were limited to a single landslide at the Dillon Dam site.

TL;DR: In this article, the authors reviewed principal topics in engineering geology in permafrost and discussed its properties, forces and energies, and only pertinent literature is quoted, and case histories and detailed treatment are omitted due to space considerations.

TL;DR: Nuclear excavation appears to be an economical, practical and beneficial utilization of nuclear explosives, however, up to the present time, the technical, political and psychological implications of this application have presented a formidable barrier to its general acceptance as discussed by the authors.

TL;DR: A critique and discussion of alternatives that involve continental separation and sea floor spreading are presented in this paper, where it is shown that the results of his stress measurement work confirm the validity of the contraction hypothesis for the evolution of the earth.

TL;DR: In this article, a very dense network of microfissuration was detected, very rich in secondary fluid inclusions, with a great number of alignments, in the Malpasset rock.

TL;DR: In this paper, the specific geology of each of the proposed sites is reviewed and the inadequacy of present information emphasised, and Geotechnical problems which might arise during and after construction of the barrages are summarized.

TL;DR: In this article, a program is presented for automated analysis of the stability of slopes by the SIMPLIFIED BISHOP'S METHOD in which only the HORIZONTAL COMPONENT of the interaction BETWEEN SLICES is considered.

TL;DR: A Village Water Supply Survey Team has been set up in the territory of Papua and New Guinea to review the current position district by district and make recommendations for the development of water supplies as discussed by the authors, and the survey team and the types of schemes considered are illustrated by reference to surveys which have been carried out in the Milne Bay and East and West Sepik Districts.

TL;DR: Two road tunnels each about 600 ft. long have recently been constructed near Monmouth on the New Midlands road, which will take the place of the existing Newport to Worcester trunk road, between Newport and Monmouth as mentioned in this paper.
