This paper presents an overview of developments and trends in the practice of supported excavations since 1990. Soil mixed walls, ground improvement and hybrid support systems are more frequently used. Design has evolved such that stiffness based approaches are common in urban areas. LRFD based design is replacing traditional allowable stress design in a number of situations. Numerical analyses of support systems have become more prevalent, especially in situations where ground movements adjacent to an excavation are important. With developments in sensors and information technology, the observational approach is becoming more automated, with near real time data available to share holders. This paper summarizes these trends and speculates how they may evolve in the future.
