According to the pavement structure dynamical analyze theory, the principle and process of the pavement modulus back - calculation have been discussed. the appliance ideas of the dynamical modulus among the pavement evaluation, the dynamical characteristic and correlative dynamical parameters of the cement concrete pavement surface, basement and subsoil have been investigated, and the contrast relationships between dynamical and static modulus of the cement concrete pavement have been established, and the evaluation standard of the structure layers " dynamical modulus of the cement concrete pavement has also been presented
根據路面結構動力分析理論，對路面模量反算的原理及實現過程進行論述，研討了動態模量在路面評價中的應用思想及水泥混凝土路面面層、基層、土基的動態特性和相關的動力參數，建立了水泥混凝土路面動態模量與靜態模量的對比關系，提出了水泥混凝土路面各結構層動態模量的評價標準。 -
The evaluation for sidthk program shows that its backcalculation procedure is stable and its accuracy is higher, furthermore, the backcalculated results are not effected by the selection of seed value at a very wide range. the accuracy of sidthk program is much better than that of current gpr data analyzing method no matter for new or aged asphalt concrete pavement and cement concrete structure. in addition, the pavement thickness backcalculation results f
對sidthk軟體考評結果顯示： sidthk軟體反算過程穩定，精度較高，而且反算結果在相當大范圍內不受初始值的影響；不論是對新鋪瀝青混凝土路重慶大學博士學位論文面，還是對舊瀝青混凝土路面和水泥混凝土板， sidthk軟體的反算精度都明顯高於現行方法的計算精度。 -
( 3 ) according to system science theories and the function principles, the thesis defines the pavement structure performance. and choose the five token road indexes which stand for pavement usage functions, namely road structure strength index ( rssi ), road quality index ( rqi ), pavement function condition pfc or sfc, pavement condition index ( pci ) and pavement environment index ( pei ), and discuss various indexes rating standard. in a word, the study and evaluation of pavement performance was established systematically, which provide a fundamental theory for the pavement management
（ 3 ）依據系統科學理論和功能原理，對路面結構使用性能進行了定義：確定了表徵路面結構使用性能的五項指標，即路面承載能力系數rssi 、路面行駛質量指數尺rqi 、路面行駛安全性能指數pfc或sfc 、路面破損狀況指數pci和路面環境性能指數pei ，並討論了各項指標的測定和分級標準，為路面結構使用性能的系統研究奠定了理論基礎。 -

It indicates that although this procedure has introduced the mechanistic - empirical method, but still is not perfect in design theory : one is about bearing capacity evaluation method and device. the currently used device - benkelman beam is dropping behind the development of the pavement testing service ; the other is about the mechanistic method that used in overlay design. it simplifies the original pavement and subgrade as a whole half infinite space, this is not true in the real layered pavement structure
綜合分析了各種罩面設計方法的原理及其優缺點，對於我國目前設計規范中所採用的罩面設計方法進行了詳細的分析與研究，指出了它雖然已經採用了力學與經驗相結合的設計方法，但仍然存在著明顯的不足之處：一方面是舊路承載能力評價設備仍然採用貝克曼梁，檢測手段落後；另一方面，在力學設計方法中，對于舊路承載能力的評估忽略了舊路面結構的分層，而是採用了近似的彈性半空間體，給出了舊路頂面的綜合回彈模量。 -
( 5 ) from the point of the pavement function request and the whole evaluation system, define the pavement quality index ( pqi ) which represents the holistic pavement structure performance, establish the evaluation model and rating standard, apply the fuzzy theory, the theory of set pair analysis and the gray system theory in the evaluation of pavement performance, and create some appraisal models
（ 5 ）從路面的功能需求和評價系統的整體出發，對路面結構綜合使用性能指數pqi進行了定義，並建立了相應的評價計算體系和分級標準，探討了模糊數學理論、集對論和灰色系統理論等在路面結構使用性能評價中的應用，建立了多個評價分析模型。 -
Along with the development of road construction, it becomes more important to the nondestructive evaluation of pavement structure
隨著我國公路建設事業的發展，對路面結構進行無破損評估日臻重要。
