ABSTRACT
Horizontally loaded piles are piles which are subjected to a horizontal load or an overturning moment or both. The design of such piles is controlled by two aspects: the allowable deflection or allowable slope of the pile top and the allowable bending moment in the pile. This chapter deals with the design of horizontally loaded piles. It presents the criteria for the design of horizontally loaded piles. Two sets of equations are used to establish the governing differential equation for the problem: the constitutive equation for the pile and the equilibrium equations for the pile element. The chapter presents the subgrade modulus approach for short rigid piles. The critical depth is a soil-structure interaction phenomenon. The closed form solution of the interaction problem in linear elasticity makes use of a key interaction parameter. The critical depth phenomenon exists also for the pressuremeter.
