The cavity assessment criterion is garded in benkelman beam experience assessment method
對貝克曼梁經驗判別法的脫空判別標準進行了分級。 -
Dynamic modulus of layers is backcalulated by sidmod program with the deflection basin measured by fwd. static modulus is determined based on benkelman beam and plate bearing data. applicability of different devices in modulus calculation is summarized. the research results of this dissertation prorided the experimental and academic basis for the spread of fwd
用fwd測得的彎沉盆計算各結構層的動模量，用貝克曼梁和承載板測得的中心彎沉計算靜模量，分析了不同設備與方法在進行模量反算時的適用性。 -
Fwd, benkelman beam and plate bearing tests were conducted on subgrade layer, subbase layer, base layer and surface layer of one selected pavement during construction in 1998. correlations between defections measured by three different test devices have been established through deflections comparison and analysis
為了研究貝克曼梁、承載板和fwd三種彎沉檢測設備在路面彎沉檢測上的相關性，我們在選定的試驗路段上進行了彎沉檢測對比試驗。 -
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。 -
