Analytical Solution of Arbitrary Loaded Spatial Pile Group
PERIODICA POLYTECHNICA-CIVIL ENGINEERING(2020)
摘要
This paper presents an analytical method for the calculation of the arbitrary loaded spatial pile group fixed or/and hinge jointed into a rigid cap. The method uses the vector and matrix procedures to derive spatial equations of equilibrium, in which unknown componential displacements appear. The stiffness coefficients in the equations can be determined analytically, numerically or by pile load test. The pile group effect are estimated approximately, reducing the piles stiffness coefficients which depend on pile position and its mutual distances.
