Geotechnical Engineering in the Coastal Zone.

摘要

This is comprehensive report providing an overview of geotechnical engineering aspects for coastal engineers to use in planning and design of coastal projects. The fundamentals of geotechnical engineering, including coastal area soil classification and engineering properties of soil analyses, are discussed first. Then, important geotechnical considerations in coastal site selection, methodologies of subsurface exploration and soil testing techniques, in the field and laboratory, are discussed in the initial chapters. The second half of this report focuses on specific types of coastal structures and the geotechnical aspects of each. Shallow foundations for gravity structures, emphasizing the bearing capacity and settlement analysis, and retaining structures, very common in the coastal area, are discussed. Particular emphasis is given to wave effects on bulkheads structures used to protect natural slopes. The final two chapters deal with slope stability relative to embankments or other man-made slopes such as breakwaters, jetties, and bulkenads as well as natural slopes. The contribution of slope instability to bluff erosion and geotechnical design procedures for planning correctives structures are also discussed.
