Showing papers in "Engineering Geology in 1968"

TL;DR: In this paper, the strength and deformation characteristics of coal pillars are investigated and a new relationship describing the strength of full size coal pillars is presented and its validity verified by experimental data.

TL;DR: In this paper, the results of research carried out during the past fifteen years on the quick clays of eastern Canada are described, and the important influence of rate of loading has revealed the need of careful interpretation of laboratory tests for field application.

TL;DR: The p-v-t diagram of ice as mentioned in this paper has been used extensively in the field of engineering geology and has been shown to be useful in estimating the minimum Pleistocene rock temperatures of felsenmeers.

TL;DR: In this paper, the suitability of a soil for stabilization, the most appropriate stabilizing agent, and the quantity of agent are determined by the chemical and mineralogical compositions and texture of soil.

TL;DR: In this paper, the suitability of 30 different types of rock used by engineers in South Africa for road construction are described and their weathering products are discussed in the light of the South African geology and climate.

TL;DR: In the case of the Alaska earthquake of March 27, 1964, quick-clay triggered by the Anchorage earthquake flowed beneath a comparatively flat lying surface veneer of gravel, sand, and silt and rafted along overlying coarser sediments and many houses as mentioned in this paper.

TL;DR: The fundamental principles of rock fragmentation by crushing, blasting, and drilling are not well understood; however, empirical observations have provided means for predicting the energy requirements for these processes as discussed by the authors.

TL;DR: In this paper, a series of folded quartzite masses rendered unstable by the construction of an access road is described, and an analysis is made of the actual and potential sliding surfaces and the deduction made that failure is prevented only by physical discontinuities in the failure planes.

TL;DR: In this article, the Slapy Dam of the river Vltava was opened in granodiorite which revealed the significant contact zone of the central Bohemian pluton and the origin of diorite inclusions.

TL;DR: In this paper, level recording and sampling took place on twelve series of settling ponds, for a period of eleven years, and the data obtained show that, as the coast is approached, the quantity of silt deposited decreases; the clay content of the warp in the ditches increases at a lower rate; and the area between the fields continues to increase.

TL;DR: In this paper, the authors used well-grained, lightly cemented, slightly clayey quartz sands, known locally as "gatch", for road base construction in Kuwait, and found that the gatch often swells in excess of 15% and loses most of its strength, the C.B.R. values decreasing to about 2% after soaking.
