摘要
对混凝土二次衬砌中的底界厚度、空洞、漏水、钢筋网变形等问题进行检测 ,是公路隧道工程施工中的关键技术。本文通过理论分析和工程试验 ,研究确定了利用探地雷达技术检测所需的有关参数选择方法和测线布置原则 ,同时验证了检测方法的精度和可靠性。研究表明 ,利用探地雷达检测公路隧道衬砌质量具有无损、快速、广泛、精确等优点。
Inspections of base thickness,cavity,leakage and the d i stortion of steel nets are the key technique in the construction of highway tunn el.Through the theoretic analysis and tests,the selection of related parameters and the principle for measuring\|line arrangement are ascertained by using groun d penetrating radar,and the precision and reliability of the inspections are ver ified.The study shows that the said inspections are of the advantages of non\|de struction,rapid,wide use and accuracy.
