高压旋喷桩水泥土电阻率与抗压强度对应关系研究

Corresponding Relationship between Electrical Resistivity and Compressive Strength of High Pressure Jet Grouting Pile Soil-cement

通过对高压旋喷桩芯样展开电阻率和抗压强度测试试验,研究电阻率与抗压强度的对应关系。测试结果表明,电阻率与抗压强度总体上存在线性对应关系,抗压强度越大,电阻率值越大,利用此规律可以将电阻率测试法应用于高压旋喷桩的质量检测,达到无损检测的目的。

According to the electrical resistivity test and compression test of soil-cement of high pressure jet grouting pile, the corresponding relationship between electrical resistivity and compression strength is investigated. The test result shows that the electrical resistivity is of linear relationship with compression strength. The electrical resistivity increase when the compression strength increase. In order to reach to nondestructive examination, the electrical resistivity test can be applied to the quality test of high pressure jet grouting pile by using the research result.
