Furthermore, authors statistic actual impacting times in the local by various types of hammer when the pile drives into the different depth of the bearing stratum, it may offer the reference for the similar engineering to choose the hammer in the future.

因此，如何对该类型的桩进行合理沉桩分析，是桩基施工中急待解决的问题。 2沉桩阻力在沉桩施工的过程中，桩锤的冲击力应大于土层的沉桩阻力，桩才能顺利下沉。

The dynamical and kinematic specialty of hydraulic hammer is analyzed during piling. At the same time, the mathematical model is presented of each process. Based on mathematical model of each stage, simulation and analysis is made. The changing rule of displacement, velocity, acceleration can come to a decision from simulation plot during falling process of pile hammer.

提出桩锤在各个打击过程中的数学模型，并对各阶段进行仿真及分析，研究桩锤下打过程中，桩锤位移、速度、加速度变化规律，为进一步研究生产样机提供了理论依据。

Studying on the hydraulic pipelines of the nitrogen-inflating hydraulic pile hammer, establishes a optimization objective function for it with the relevant methods of parameter optimization, and uses Matlab to solve the model, gets a group of optimization pipelines size, and tests the validity of this method. So more efficiency methods for hydraulic system design of the nitrogen-inflating hydraulic pile hammer are provided.

以氮爆式液压打桩锤液压管道为研究对象，应用参数优化设计的相关方法建立氮爆式液压打桩锤管路优化分析的目标函数，并利用Matlab编程对模型进行求解，得出一组优化后的管道尺寸，并检验这种优化方法的有效性，为氮爆式液压打桩锤液压系统的设计开发提供了更为有效的方法。
