This is the first publication of the proceedings of the Baltic Geotechnical Conferences after Baltic countries regained their independence and became member of the ISSMFE as free states. The Baltic countries have old construction traditions going back to almost a thousand years. The proceedings present an outline of the current situation in the Baltic countries. A few reports from other European countries have also been included. The themes treated embrance a wide scope of geotechnical problems solved in the Baltic countries taking into account their current economic conditions of transition from a state-regulated economy to that of a free market.

The US Symposium on Rock Mechanics, held at Lake Tahoe, California/Nevada, is the 35th in a continuing series of now biennial meetings organized to support the national and trans-national interests of US scientists, engineers, consultants, students, and technologists interested in rock mechanics and rock engineering. The reviewed papers contained in this volume represent one or more aspects of this interdisciplinary field. This volume contains a total of 133 papers selected from 241 abstracts, in addition to 2 invited papers prepared on broad multidisciplinary issues. Session topics include: Construction; surface excavation; stability and shear strength of fractured rock; laboratory testing; rock dynamics; stress measurements; tunnels and groundwater flow; petroleum; tool-rock interaction; building stone durability; rock reinforcement; fracture mechanics; radioactive waste disposal; underground mining; fragmentation and blasting; metal mining, coal mining; planetary rock mechanics; rock properties; stochastic methods; theoretical and model studies; hydrology; and rock creep. Field trips and informal discussions associated with the symposium form an integral part of technical and social interaction among participants. Although much attention is devoted in the technical program to areas of major national concern in which rock mechanics problems represent critical or limiting factors - including energy, tunneling and excavation, waste disposal, and reactor siting - papers were sought and received with the widest possible scope of research and applications.

Over the past decades a great variety of anchor types has been developed for a multitude of different applications in soils, jointed rock or homogeneous concrete, and thus the experiences gained served a basis for futher development. Special importance was attached to the design of permanent anchors with protection against corrosion and to in situ monitoring in order to ensure the permanent contribution of anchors to the stability of the structure. More than 50 papers are focussing subjects that are of interest to designers, manufacturers, contractors and owners and are dealing with the topics load bearing capacity and effect of anchors, history cases, types of anchors as well as protection against corrosion and long term behaviour.

16 European countries are represented & the contributions demonstrate vigorous activity across a range of interests, but emphasise the importance of practical application of numerical techniques. Several papers address the problem of localised deformations, so important in many geotechnical situations involving shear banding. Specific areas of practical application include thermo-mechanical problems, tunnels & pipelines, foundations, reinforced soil, retaining walls, slopes & rock mechanics. This volume is essential reading for everyone wishing to keep abreast of the techniques of modern computer analyses applied to geotechnical engineering practice.

Comprises the proceedings of a conference on geotechnical waste management and contamination. Coverage ranges from remediation of contaminated sites to design and management of landfills. There are also papers dealing with case histories and research.

Contents: Groundwater contamination flow; Regulatory, & non regulatory controls for contaminated sites; Remediation of contaminated sites; Ground modification techniques in waste management;
