高速公路养护期立柱埋深无损检测影响因素辨识与精度控制

Identification of influencing factors and accuracy control of column burial depth during highway maintenance period

高速公路养护期的立柱埋深具有隐蔽性和不确定性。对于立柱埋深检测多采用无损检测方法,分析高速公路养护期立柱特点,针对养护期护栏立柱埋深无损检测信噪比影响因素进行辨识。

The buried depth of the column in the maintenance period of the expressway is hidden and uncertain. Nondestructive testing(NDT) method is often used to detect column burial depth,and the characteristics of the column during maintenance period of expressway are analyzed. The factors influencing the SNR of column burial depth during maintenance period of guardrail are identified.
