### Application of Generalized Load Transfer Function in Clay

#### Abstract

So many load transfer functions are more and more widely used in pile foundation engineering. Since the generalized load transfer function is difficult to use, Abaqus is employed to simulate the friction behavior between pile and soil to get the range of parameter n of generalized load transfer function in clay. Furthermore, the impact of different parameters of clay on the value of n was investigated, and it was obtained that when the elastic modulus of clay increases, the value of n also increases. And the increasing trend gradually increases as well. When the cohesion increases, the value of n also increases. However, the increasing trend gradually decreases. When the internal friction angle increases, the value of n increases too, but the increasing trend decreases. When the Poissonâ€™s ratio increases, the value of n decreases, and the decreasing trend increases. When the density of soil increases, the value of n decreases, but the trend of decreasing decreases. Finally, a Fortran program is developed to calculate one example, the calculation result is close to the result of experiments in the example, and shows that generalized load transfer function is well fitted in the pile soil interface contact problems.
