A method for terrain classification based upon geology, geomorphology, pedology and botany is proposed as a basis for listing of the required geotechmlcal properties. The system proposed is hierarchical in nature with each mender of each class composed of a limited constant re- petitive association Of members of the preced- ing class. A system for n~rical nomenclature of the terrain classes is proposed so that in- formation collected will be compatible with processing in a computer medium.

792249 APPLICATION OF AIR-FLUSH ROTARY-I~CUSSION TECH- NIQUES IN SITE INVESTIGATION

Horner, P C; Sherrell, F W Q J Er~ Geol, VlO, N3, 1977, P207-221

This involves t h e drilling of boreholes under controlled comditlons, measuring t h e rate of penetration, observing the drilling character- istics and sampling the drilling flushings, so that the rock type may be identified ard some aspects of its geotechnical bahaviour interpreted. Applications ani limitations of the technique are discussed, with case studies in Devoz~ amd Corr~all I including the location of voids and of geological boundaries.

Grainger, P; McCann, D M Q J Engng ~oi, VIO, N3, 1977, P2~I-255

The experimental procedure for this technique is described. The instrumentation used includes an energy source in the form of an enclosed electrical sparker. Two case histories s from the Dincrwic hydro-electric scheme in North Wales and from Whatley Quarry near Frome in Somerset, ere presented to show the nature of the interpretation process and the quality of geological data that can be achieved. At Dino- rwic the technique was used to study dam foun- dation comditions, and at Whatley to locate water-bearing fissures and cavities.

CarteD, D J; Hart, M B Q J Engng Geol, V10, N3, 1977, P321-338

The Thames Barrier, nG~ urzler constl~action between Woolwich an~ Sllvertown, will protect central London from tidal flooding and will con- sist of a saries of rotatable gates supported by concrete piers, the majority of which are founded in the chalk b~Irock. The study repor- ted here was to provide a stratigraphic corre- lation of the upper chalk across the site, to locate the position of faults and of boundaries between undisturbed in situ chalk and disturbed (solifluction or frost-shattered) chalk. Core samples from 68 bore~holes ~ere examined for faunal distribution and the data interpreted geologically.

Describes the use of satellite and aircraft imagery for evaluating mine ground stability. The mine sites have included coal, metal, and nonmetal open pit and underground operations in various geologic environments. Underground and surface investigations were conducted to

co~firm llmear orientations and density. Frac- ture orientations observed as li~ars o n imag- ery have been eor~irmed at mime levels over 2000 ~eet deep and in areas of extensive un- consolidated overburden. Ground stability in mines more than 50 miles a/tort has been affec- ted by fractures represented by the same en echelon satellite linear trend.

The ground conditions associated with old mine- shafts are reviewed and the two geophysical me- thetis used for detection, the resistivity and the magnetic method are discussed briefly. Two case histories concerned with an industrial estate and t h e proposed line for a main sewer in tunnel are described in detail. The magnetic method was used in both cases.

Reports tests carried out in a seam of a Polish mine. Geophones were installed 40 to 100m ahead of the working face and the wave velocity resu- lting from controlled blasting was determined. Impulse centres were located from differences in the times of arrival of subsequent impulses, using the known velocity of wave propagation. With sharp impulses the location error was less than 10m.
