The papers in this volume are primarily concerned with the theory, design and practice of artificial ground freezing (AGF) and with frost heave, frost penetration and thermal degradationof frozen layers in seasonal frost areas. It contains papers on the following topics: Heat and mass transfer; Frost susceptibility and frost heave; Mechanical properties; Environmental soil freezing; Engineering design and Case histories. It also contains reports from working groups within the ISSMFE technical committees on Frost (TC8) and on Ground Freezing (TC23).

Geosynthetic-Reinforced Soil (GRS) structures have gained increasing popularity in earthwork construction in many parts of the world. In actual construction, GRS structures have continued to demonstrate many distinct advantages over their conventional counterparts. GRS structures are typically more ductile, more flexible, more economical, more adaptable to low quality backfill, and easier to construct. This book contains the proceedings of the International Symposium on Mechanically Stabilized Backfill. It comprises four parts: Five keynote presentations delivered by premier researchers and engineers from US, Japan, France, Italy and Canada; 26 technical papers by practitioners and researchers of reinforced soil technology; A special presentation on the performance of 7,6-m high prototype reinforced soil bridge piers and bridge abutment; Panel discussion on 4 volatile subjects: long-term deformation, connection strength, and seismic performance and design. The panel discussions feature presentations by renown experts on each subject. The ensuing floor discussions of each panel discussion is also included in the book. This unique forum shall help designers and researchers understand the divergent aspects and relative significance of each of the issues.

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.

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.

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.
