Measurement of earth pressures by means of the flat jack test
P. Habib, R. Marchand, Severine Britt (translator)
1953, Open-File Report 54-31
This study deals with the principle and application of a method of measuring the stresses around a rock gallery. The measuring principle consists of cutting a drain in a gallery wall, observing the corresponding stress lessening, then restoring the initial state of stress by means of a Freyssinet flat jack. The...
Marine geology of the Near Islands Shelf, Alaska
Philip Challacombe Scruton
1953, Open-File Report 53-245
During the summer of 1950 on the insular shelf surrounding the Near Islands, Alaska, 193 oceanographic stations were occupied from aboard the U. S. Geological Survey vessel EIDER. Bottom character and temperature observations were made at these stations. The composition and size distribution characteristics of the bottom samples have been...
Clay deposits of the Tierra Colorado district, southern Orange County, California
Steven Norman Daviess, M. N. Bramlette
1953, Open-File Report 53-51
The clay of this district is being mined for fire brick by the Vitrofrax Corporation. Much of the clay contains 35 percent or more of alumina and between 1 and 2 percent of iron oxide. Production is largely from an underground mine as the best clay deposit known in the...
Preliminary report on the Little Susitna district, Matanuska coal field, Alaska
Farrell F. Barnes
1953, Open-File Report 53-10
The Little Susitna district, as defined in this report, occupies an area roughly 25 miles long and 3 miles wide on the north side of the lower (western) extremity of the Matanuska Valley in south-central Alaska (fig. 1). The district is bounded on the north by the Talkeetna Mountains, on...
Measurement of earth pressure in the iron-ore mines of eastern France
M.E. Tincelin
1953, Open-File Report 54-30
The purpose of the tests, which will be reported later, is to measure as precisely as possible the tangential stresses exerted on the periphery of a gallery cut in the Lorraine iron ore. The values of the tangential stresses along the periphery being known, they will be compared with the values...
