Reliability-Based Design in Geotechnical Engineering [PDF ebook] 
Computations and Applications

Reliability-based design is the only engineering methodology currently available which can ensure self-consistency in both physical and probabilistic terms. It is also uniquely compatible with the theoretical basis underlying other disciplines such as structural design. It is especially relevant as geotechnical design becomes subject to incre
