| 摘 要： | 喷粉桩属半钢半柔性桩,均质性较差,桩身横断面不均一。因此理论上讲,它很难满足适用于钢性桩应力波反射波法测试的各种完整性检测方法所具备的系列基本假设。这也正是喷粉桩完整性应力波反射波法其完整性检测引起争议的主要原因。本文尝试将该法用于喷粉桩完整性的检测时,用频谱分析方法处理其所获取的信号,取得了较满意的效果。 |
| 关 键 词： | 反射波法 喷粉桩 完整性检测 频域 |

| Abstract: | Stir coment and soft soil in deep ground pile is semi plastic pile. The pile body was mixtured by cement and clay. The cross section is homogeneity. So in theory, it absolutely hard to fit the supposes of all kind that the method of stress wave reflect to examining complete to reinforced concrete pile. That just right caused dispute that the method of stress wave reflect to examine it. The paper tried making the method of stress wave reflect to examine stir coment and soft soil in deep ground pile, and analysis the signal and processing it by the method of frequency is good. |
| Keywords: | the method of reflect stir cement and soft soil in deep ground complete examination frequency domain |
