Abstract


The paper establishes the three dimensional soil body finite element model by using ANSYS in the foundation of the synthetic study to formerly the research results and exerts the strength the time interval function on the soil model to simulate the function which the driving hammer to attack on the ground. The paper confirms the soil model and in each kind of controlled variable value of the soil model by contrasting the test result with computational solution. To the earth elasticity coefficient value aspect, the paper uses a simple experiment to be possible to calculate its number range which provides a basis in the later similar theory analysis. This paper confirms the above analysis conclusion by analyzing empirical datum in the time domain and the frequency range. A trench isolation is obvious effects by analyzing and researching the results which use trench isolation in the surface vibration.This paper summarized the actual vibration wave several methods and vibration of the spot source influencing in the environment. For reasons given above , I obtain regression formula which show the discipline with distance change in the vertical, tangential and the radial direction of vibration of the spot source , conducts the researchand the comparison to this formula.
