强夯法具有施工简便、效果明显和适应性广等优点，成为软弱地基加固的主要方法之一，在沿海地区的基础设施建设中应用广泛。为深入研究强夯法加固地基机理，认清相关规律，利用有限差分软件FLAC3D，以三角形波和正弦波代替夯锤与地基接触时产生的应力波，并对两种波形产生的能量传递进行模拟研究。研究表明：三角形波适宜在表层土质较坚硬的强夯加固，正弦波适宜在表层土质软土的强夯加固。

Dynamic compaction method had advantages of simple construction,obvious effect and wide adaptability,which become one of the main method of soft foundation reinforcement,widely used in the construction of infrastructure in the coastal area. To lucubrate the foundation reinforcement mechanism and identify relevant laws,used the finite difference software FLAC3D,replaced the rammer with triangle wave and sine wave generated when in contact with the foundation of stress wave,and the two kinds of waveform simulation studies of energy transfer. Studies showed that the triangular wave was appropriate in the consolidation of the surface hard soil,sine wave was appropriate in the consolidation of the surface layer soft soil.
