摘  要：為精確檢測(cè)鋼筋混凝土中保護(hù)層厚度、鋼筋的直徑及其間距，采用SIR-4000型地質(zhì)雷達(dá)（GPR）對(duì)某一鋼筋混凝土路段進(jìn)行無損檢測(cè)，測(cè)得的雷達(dá)圖像與實(shí)際路段進(jìn)行對(duì)比分析。結(jié)果表明，混凝土保護(hù)層厚度，鋼筋直徑、間距均與實(shí)際工程情況一致，偏差值均小于1%，滿足質(zhì)量檢測(cè)要求。

關(guān)鍵詞：地質(zhì)雷達(dá);鋼筋混凝土;質(zhì)量檢測(cè);參數(shù);數(shù)據(jù)

Abstract： In order to accurately detect the thickness of cover and the diameter and spacing of steel bar in reinforced concrete， this paper uses SIR- 4000 ground penetrating radar （GPR） to carry out non-destructive testing of a reinforced concrete road section， and compares the radar image with the actual road section. The results show that the thickness of concrete cover， steel bar diameter and spacing are consistent with the actual engineering situation， and the deviation values are all less than 1%， which meets the requirements of quality inspection.

Keywords： ground penetrating radar （GPR）; reinforced concrete; quality inspection; parametor; data
