深层搅拌桩搅拌头结构和动力特性对桩体搅拌均匀性的影响

The Effect of Mixing Bit Dynamics and Structure on Uniformity of CDM Pile’s Body

摘要:

通过对搅拌头叶片的动力特性和切削搅拌机理分析，阐明影响桩体搅拌均匀性的主要因素是叶片的水平旋转速度和垂直运动速度，分析了搅拌头结构形式对搅拌均匀性的影响，提出了提高搅拌均匀性的途径。

Abstract:

Based on the analysis on the dynamics and the cutting & mixing mechanism, the paper explained that the main factors which effect mixing uniformity of deep mixing pile body are the horizontal rotary velocity of the blade and the vertical motion, and analysis was also made on the effect of structure of stirrer to mixing uniformity. The approaches and measures to improve mixing uniformity were put forward.
