This chapter presented MARS approach for estimating wall deflection profile caused by deep braced excavations, based on an expanded database including a total of 30 case histories for braced excavation in stiff, medium, and soft clays. Seven input variables, including wall length, excavation depth, excavation length, system stiffness, average unit weight, undrained shear strength of the soil, and the depth below the ground surface, are adopted as inputs to the MARS deflection profile model. Comparison with two more excavation case histories indicates that the developed MARS model can give an accurate graphical representation of the wall deflection profile. It is capable of not only predicting the value of maximum wall deflection but also estimating the possible depth at which maximum lateral deformation occurs.
