Design And Performance Of Earth Retaining Structures

Design and Performance of Earth Retaining Structures

Proceedings of the 1990 Specialty Conference on Design and Performance of Earth-Retaining Structures, held in Ithaca, New York, June 18-21, 1990. Sponsored by the Geotechnical Engineering Division of ASCE. This Geotechnical Special Publication contains 50 papers on the design and performance of earth-retaining structures. Topics include historical perspectives, wall selection, contracting practices, waterfront structures, gravity walls, mechanically stabilized systems, cast-in-place walls, soil nailing, tied-back excavations, and seismic design. Papers survey the current state of the practice for earth retention and support, detail the rapid and profound changes to design and construction practices in the past 20 years, and forecast technological developments that are likely to carry the practice into the next century. Sixteen invited papers by international experts address aspects of each of the general topics, including trends in ground movements, effects of material selection and construction practices, and advances in design analyses and procedures. Other papers address specific case histories of various types of earth-retaining structures, provide results of performance monitoring, compare predicted to actual performance, and assess the impacts of construction practice and design procedures on performance.

Numerical Modelling of Construction Processes in Geotechnical Engineering for Urban Environment

It has become increasingly important, particularly in an urban environment, to predict soil behaviour and to confine the settlement or deformation of buildings adjacent to construction sites. One important factor is the choice of construction procedure for the installation of piles, sheet pile walls, anchors or for soil improvement techniques, ground freezing and tunnelling methods. The modelling of construction processes, which are frequently associated with large deformations of the soil and with strong changes in the structure of the soil around the construction plant, in the case of, for example, a drill, a bit, a vibrator, or an excavation tool, requires sophisticated and new methods in numerical modelling. Often the simulation of the construction procedure is neglected in the calculations. Such methods are described and discussed in this book, as are examples of the methods applied to geotechnical practice, field and laboratory testing as well as case studies. This volume provides a valuable source of reference for scientists in geotechnical engineering and numerical modelling, geotechnical engineers, post graduate students, construction companies and consultants, manufacturers of geotechnical construction plants and software suppliers and developers of geotechnical construction methods.
