Fitting method for determining the ultimate bearing capacity of flexible batter piles in clay under lateral loads

摘要

Generally, it is difficult to read tile ultimate bearing capacity of flexible barter piles under horizontal loads from load Q-deflection Y curves. Manoppo et. al has been done in case of single flexible barter piles m sand under horizontal loads for determining the ultimate bearing capacity by using the fitting method. In continuation of the previous investigation tile present paper is presented tile fitting method for the calculation of the ultimate bearing capacity of single batter pile driven into clay under lateral loads and its applicability is discussed experimentally. Model experiments were carried out using flexible piles of wide-ranging flexibilities The piles were pushed into clay at batter angle #beta# =0 deg, +-15 deg, +-30 deg and were subjected to incrementally increasing lateral loads The present theory of ultimate bearing capacity was found in reasonable agreement with the theory suggested by Meyerhof.
