挪威工学院土力学教授N.Janbu是国际著名学者,是挪威土工研究所和挪威工学院土工专业的创始人之一。他在土力学研究中提出了广义正切模量、抗剪强度发挥程度及Janbu孔隙水压力系数等一系列基本定义与概念,并将其应用于土中应力与变形、强度与稳定性的计算中。他的理论和方法与目前广泛应用的土力学计算理论和方法有明显的不同与特点,不仅 N.Janbu, professor of soil mechanics at the Norwegian Institute of Technology, is an internationally renowned scholar and one of the founders of geotechnical engineering at the Norwegian Geotechnical Institute and Norwegian Institute of Technology. In his study of soil mechanics, he proposed a series of basic definitions and concepts such as generalized tangent modulus, degree of shear strength, and Janbu pore water pressure coefficient, and applied them to calculation of stress and deformation, strength and stability in soil. . His theories and methods are obviously different from the widely used methods and methods of calculating soil mechanics.
