Showing papers in "Engineering Geology in 1977"

TL;DR: In this article, the authors present an up-to-date review of CABI research, based on a study of samples from many countries, classical localities and particular sediments.

TL;DR: In this article, the authors reviewed lime stabilization of lateritic soils and showed that all Nigerian lateritic soil from A-1-a soil to A-7-6 soil used in the investigation, improved their engineering characteristics substantially by the addition of lime.

TL;DR: Witherspoon et al. as discussed by the authors considered the role of fractures in induced seismicity and found that the time required to achieve quasi-steady state flow in a fractured reservoir is one or two orders of magnitude greater than it is in a homogeneous system.

TL;DR: In this article, the authors investigated the relationship between the sesquioxide content and other physical and engineering properties of Eastern-Nigeria laterites and concluded that no correlation was found between ironoxide content and any other physical or engineering properties as has been suggested by others.

TL;DR: In this paper, the specific gravity and void ratio of basalt basalt is used to predict the field performance of lateritic basalt soils, and the results suggest a classification based upon specific gravity this paper.

TL;DR: The Upper Chalk of Kent is characterized by a high porosity and relatively low dry density, whereas the lower and middle chalk of Yorkshire and Middle Chalk are lower and higher respectively, due to higher content of interstitial secondary calcite as discussed by the authors.

TL;DR: In this paper, a logical sequence to a previous study on thermal fatigue and the weatherability of some igneous rocks by means of laboratory tests is presented, where the techniques are applied to several non-igneous rocks, such as limestones (seve al types), sandstones, graywackes and slates.

TL;DR: A general survey of limestone deposits in Nigeria is presented in this article, where five locations representing the geographical distribution of these deposits were selected and hydrated lime prepared from them, and an A-7-6 lateritic soil was stabilized with these locally prepared hydrated limes as well as a commercial lime.

TL;DR: In this article, repeated levelings conducted by the National Geodetic Survey indicate a zone of anomalous relative subsidence in the vicinity of Pecos, Texas, which appears to have resulted from the decline of water level due to pumping from unconsolidated stream-deposited alluvium of Cenozoic age.

TL;DR: A field investigation made to ascertain if recognisable fracture patterns exist within the Chalk of southern England is described in this article, where the areas investigated included: the Chilterns the Isle of Thanet; the South Downs; and the Isle Of Wight.

TL;DR: Joint controlled weathering and sub-basaltic weathering at Victorian dams has been investigated in the literature as mentioned in this paper, where the relevant barriers, the limonite-coated joints, are themselves the product of earlier weathering, providing the avenue for water penetration into the rock mass bound by the joints.

TL;DR: Sauer et al. as mentioned in this paper investigated the types of problems that can occur in highways constructed across these channels, including instability, groundwater control and excavation through a boulder pavement, and demonstrated how these problems can be resolved by establishing the geology of the sites and designing to preclude geotechnical problems.

TL;DR: Instrumentation for observations of seismicity and ground acceleration near artificial reservoirs is evolving rapidly at the present time as mentioned in this paper and increased use is now being made of larger arrays of detectors together with telemetry, storage of data on magnetic tape and even digital recording in the field.

TL;DR: In this article, a description of the toe-failure process of the waste dump formed at an open-cast mine is presented, which is caused both by the occurence of plastic clays in the subgrade and the manner of dumping.

TL;DR: In this article, the authors describe how an artificial recharge of water between some caverns is made and the control of its effectiveness is shown as well as the method for sealing off undesirable leakage.
