Analysis of Hydraulic Hammer Capacity under Different Inclination

In the existing construction of raked piles, the influence of inclination on the capacity of hydraulic hammers still needs to be explored. This paper focuses on the analysis of the ascending and descending process of the hammer during piling. The mathematical model of hydraulic hammer motion is established by Simulink, and the simulation calculation is carried out to obtain the system pressure, hammer velocity and acceleration during movement. The results show that the velocity and acceleration fluctuate within a certain range due to pressure fluctuations inside the hydraulic hammer. Compared with the hammering process of the vertical piles, the data proves that when the hammer works, the blow energy and frequency are lower. This paper can analyze the applicability of hydraulic hammer for oblique pile and provide technical support for the construction of raked pile foundation.
