( 2 ) interfacial agents this experiment adopts three types of interfacial agents : no interfacial agent, neat cement paste which has the same water - cement ratio with the new concrete, cement paste mixed with 10 % expanding agent which has the same ratio with the new concrete ( which is called cement paste mixed with expanding agent for short ). the thickness of the interfacial agent is 2 ~ 3mm
（ 2 ）粘結劑本試驗採用三種粘結劑：無粘結劑、同新混凝土相同水灰比的水泥凈漿、摻10 u型膨脹劑的同新混凝土相同水灰比的水泥凈漿（以下簡稱水泥膨漿） 。界面劑的厚度一般為2 3mm 。 -
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。 -

Based on the calculation methods of nominal water - cement ratio of mortar and average paste thickness of standard sand provided by authors, the nonlinear relation between fluidity of mortar and nominal water - cement ratio of mortar, average paste thickness of standard sand, fly ash - binder ratio was established by using artificial neural network ( ann )
摘要在給出水泥膠砂名義水灰比和標準砂平均漿體厚度計算方法的基礎上，採用人工神經網路方法，建立了水泥膠砂流動度與水泥膠砂名義水灰比、標準砂平均漿體厚度、粉煤灰與膠凝材料用量比之間的非線性映射關系。 -
The current gpr data analyzing method for pavement thickness can only give the acceptable results for new asphalt concrete pavement, but for aged asphalt concrete pavement and cement concrete pavement, the accuracy is not satisfactory because of the theoretic modeling and data acquisition difficulties. the study on pavement compaction, moisture content and asphalt content is under exploration and the program for processing gpr data based on rigorous theoretic model can not be found in literature
由於理論模型及信號採集等方面的困難，現行路面雷達厚度分析方法僅對新鋪瀝青混凝土路面有相對較好的檢測精度，而對舊瀝青混凝土路面和水泥混凝土路面的檢測精度卻不能令人滿意，對路面其它技術指標如壓實度、含水量以及瀝青含量的研究還處于探索階段，建立在嚴密理論模型基礎上的數據分析軟體系統尚處于空白狀態。 -
On the basis of analyzing characteristics of the cement - based capillary crystalline waterproof materials, the article points out that both waterproofing and leak - stopping ability of this kind of materials should be simultaneously functioned in order to enhance quality of coating layer, ensure its thickness and effectiveness
