不同桩型低应变激振方式的技术探讨

ANALYSING OF THE IMPACT WAYS IN LOW-STRAIN METHOD OF DYNAMIC PILE TESTING FOR PILES

通过分析应力波传播及其能量衰减的影响因素 ,和不同桩型的桩—土作用机理 ,结合大量实际检测资料的对比分析 ,探讨低应变动测选取激振方式的重要性。

By analysing the affecting factors that stress wave propagation and damp of stress wave energy in the pile,and the relations of pile-soil for varied kinds of piles,this paper discusses the importance of the impact ways in low-strain method of dynamic pile testing,and compares a lot of testing results.
