TAILIEUCHUNG - Ebook Principles of Geotechnical Engineering

Principles of Geotechnical Engineering was originally published with a 1985 copyright and was intended for use as a text for the introductory course in geotechnical engineering taken by practically all civil engineering students, as well as for use as a reference book for practicing engineers. The book was revised in 1990, 1994, 1998, 2002, and 2006. This Seventh Edition is the twenty-fifth anniversary edition of the text. As in the previous editions of the book, this new edition offers an overview of soil properties and mechanics, together with coverage of field practices and basic engineering procedures without changing the basic philosophy in which the text was written originally. | CONVERSION FACTORS FROM ENGLISH TO SI UNITS Length: Area: Volume: 1 ft 1 ft 1 ft 1 in. 1 in. 1 in. ϭ m ϭ cm ϭ mm ϭ m ϭ cm ϭ mm Coefficient of consolidation: 1 ft2 1 ft2 1 ft2 1 1 1 ϭ ϫ 10Ϫ4 m2 ϭ cm2 ϭ ϫ 102 mm2 ϭ ϫ 10Ϫ4 m2 ϭ cm2 ϭ mm2 1 ft3 1 ft3 1 1 ϭ ϫ 10Ϫ3 m3 ϭ ϫ 103 cm3 ϭ ϫ 10Ϫ6 m3 ϭ cm3 Hydraulic conductivity: 1 ft/min 1 ft/min 1 ft/min 1 ft/sec 1 ft/sec 1 in./min 1 in./sec 1 in./sec ϭ m/min ϭ cm/min ϭ mm/min ϭ m/sec ϭ mm/sec ϭ m/min ϭ cm/sec ϭ mm/sec ϭ N ϭ ϫ 10Ϫ3 kN ϭ kgf ϭ kN ϭ kN ϭ ϫ 10Ϫ3 metric ton ϭ N/m 1 lb/ft2 1 lb/ft2 1 . ton/ft2 1 kip/ft2 1 lb/ ϭ N/m2 ϭ kN/m2 ϭ kN/m2 ϭ kN/m2 ϭ kN/m2 Unit weight: ϭ ϫ 10 mm ϭ ϫ 10Ϫ4 m3 1 lb 1 lb 1 lb 1 kip 1 . ton 1 lb 1 lb/ft Stress: 1 in. 1 5 ϭ cm2/sec ϭ ϫ 103 m2/yr ϭ cm2/sec Force: Section modulus: 3 1 1 1 ft2/sec 1 lb/ft3 1 lb/ ϭ kN/m3 ϭ kN/m3 Moment: 1 lb-ft 1 lb-in. ϭ N · m ϭ N · m Energy: 1 ft-lb ϭ J Moment of inertia: 1 1 ϭ ϫ 106 mm4 ϭ ϫ 10Ϫ6 m4 3 CONVERSION FACTORS FROM SI TO ENGLISH UNITS Length: Area: Volume: Force: 1m 1 cm 1 mm 1m 1 cm 1 mm 2 1m 1 cm2 1 mm2 1 m2 1 cm2 1 mm2 ϭ ft ϭ ϫ 10Ϫ2 ft ϭ ϫ 10Ϫ3 ft ϭ in. ϭ in. ϭ in. ϭ ft ϭ ϫ 10Ϫ4 ft2 ϭ ϫ 10Ϫ6 ft2 ϭ 1550 ϭ ϭ ϫ 10Ϫ2 1 N/m2 1 kN/m2 1 kN/m2 1 kN/m2 1 kN/m2 ϭ ϫ 10Ϫ3 lb/ft2 ϭ lb/ft2 ϭ . ton/ft2 ϭ ϫ 10Ϫ3 kip/ft2 ϭ lb/ Unit weight: 1 kN/m3 1 kN/m3 ϭ lb/ft3 ϭ lb/ Moment: 1N·m 1N·m ϭ lb-ft ϭ lb-in.
