摘　　要：采用波动方程法模拟打桩过程中承载力、贯入度、拉应力和压应力、桩输入能量的变化，以便了解打桩过程中可能出现的问题，并提出解决方法。打桩全程的分析，可以了解打1根桩的时间和总锤击数，以便安排打桩工作。Wave equation was adopted to simulate the bearing capacity, penetration, tensile stress and compressive stress of pile, as well as variation of pile energy input during pile driving, so as to find the problems possibly appeared during piling and advance relevant solutions. Through analyzing the whole process of piling, we can know the time and total times of hamming needed for driving one pile, which will provide a reference for arrangement of pile driving.
