بنیادهای یخ‌دائمی: وضعیت عمل (مونوگرافی شورای فنی مهندسی مناطق سرد)

As building expands in the northern latitudes, it is critical to get information about soil conditions and geotechnical and structural issues in the hands of those dealing with the many challenges of building on frozen soils. Permafrost Foundations: State of the Practice presents the most current techniques used to design and construct foundations on permafrost. Failure to understand the complexity of technical issues involved in building under these extreme conditions can start with the settlement or jacking of the soils, and result in conditions ranging from sloping buildings to swayback roofs to complete structural collapse. This monograph includes eight chapters, which present the authors experiences in both the design and remedial actions required for the continued successful performance of these systems. It will be beneficial to geotechnical engineers, structural engineers, and anyone involved in design and construction on frozen soils MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict MuPDF error: syntax error: invalid key in dict Contents 8 Chapter 1 Introduction 10 Chapter 2 The Need for Geotechnical Investigation 14 Chapter 3 Structurally Enhanced Foundations: A Functional Solution to Thaw Strain in Frozen Sand and Gravel 19 Chapter 4 Post and Pad 27 Chapter 5 Adjustable Foundation Design Development Innovations in Arctic Engineering 29 Chapter 6 Marginal Permafrost a Foundation Material in Transition 39 Chapter 7 Some Case Histories of Pile Foundations in Permafrost 59 Chapter 8 Refrigerated Foundations 74 Index 92 A 92 B 92 C 92 D 92 F 92 G 93 H 93 I 93 J 93 K 93 L 93 M 94 N 94 P 94 R 94 S 94 T 95 U 95 V 95 W 95 X 95 Y 95 Content: Introduction / Edwin S.
