The constructionspeed of highwayincreases rapidly, at the same time, the path qualityexaminationdutyaggravatesdaybyday, andtheload ofroads evaluationalsoincreases quicklyin the maintenance. traditional method has many disadvantages, such asinefficiency, tiring, slow speed of evaluation etc. especially, the number ofmeasuring point is too little to give accurate and comprehensive result of theinterior recessive diseases of highway. beside this, the traditional method leadsdestructiontotheroadsurface, whichwillexacerbatethedeteriorationofhighway. in avoid not to affecting the normal travel and not to destroying the pavementstructure, it is urgently to apply nondestructive evaluation ( nde ) techniques tocontrol quality of highway construction and to estimate the running conditionaccurately. the nde techniques of highway have to satisfy the followingqualification : mapping the shape, size and depth of flaw precisely ; having nodamages to the road structure ; being capable of carrying out examination in widerange ; beingeasytoequipandoperate ; beinginsulatetotheenvironmentinfluence. theintelligenceintegrationevaluationvehicleforroadbedandpavement ( iievrp ) is just the comprehensive nde technique that can satisfy the demands above, which can implement detection of highway rapidly and nondestructively
作為吉林省科技廳高新技術項目（ 20020331 ） 「路基路面智能集成檢測車」的一個子項，本文在理論的基礎上，結合實驗對探地雷達檢測路面結構層厚度及路基、路面病害進行了研究，主要工作如下: 1 .闡述探地雷達發展的歷史和研究現狀，介紹探地雷達在路面結構層厚度檢測與路基、路面病害識別上的應用，分析探地雷達設備性能，探討其測量參數對探測性能的影響; 2 .引入matlab計算軟體，利用其中的小波分析工具箱對探地雷達信號進行分析處理; 3 .構建適于道路檢測的車載實驗平臺，為進一步完善路基路面檢測車系統打下了基礎; 4 .通過對模型的檢測，對探地雷達探測性能做出定性或半定量的評價; 5 .通過對實際路面的檢測，驗證探地雷達在道路檢測中的有效性。 -
