  1. The paper is based on the construction of the express - highway between yiyang and changde in hunan province, aiming at enhancing the serviceability of cement concrete pavement, probing into the structural assemblage of the cement concrete pavement, the roadway drainage system, contraction joint with the dowel bar and precaution of bumping at the end of the abutment. it presents some achievements of the research, including more reasonable structural assemblage and roadway drainage system, the method of setting dowelled bar in contraction joint, putting forward the concept of stage - transition from rigid to flexile behind abutment

    本文以湖南省益陽至常德高速公路項目為依託,以提高水泥混凝土路面使用性能為目標,就水泥混凝土路面結構組合、路面排水系統、縮縫設置傳力桿、橋頭跳車問題的防治等方面開展研究和工程實踐,取得了豐富的研究成果,如研究採用了更合理的路面結構組合,設置了較完善的路面排水系統,在國內高速公路上率先全面採用縮縫加傳力桿技術,對所有橋涵構造物臺背全部採用剛柔過渡技術處理橋頭跳車問題等。
  2. Pavement serviceability performance

    鋪面服務績效
  3. In order to adapt the maintenance activities well, this paper makes some ameliorations, as follows : ( 1 ) it is considered not so pertinent in this paper to take road user cost into account of total cost, and an advice of using pavement serviceability performance for benefit is given. ( 2 ) when evaluating the average of the road network serviceability, this paper put forward to using weighed geometric mean to calculate pqi. ( 3 ) bringing in a new idea of checking the reasonability of classifying pavement state and typical measure by transfer probability

    為盡可能使其反映實際的養護規律,本文在前人研究的基礎上,提出以下改進: ( 1 )在建立費用模型時,認為在我國現階段,考慮用戶費用有不妥之處,提出以路面使用性能作為用戶費用的映象,以路面使用性能作為效益的評價指標; ( 2 )在評價路網平均服務水平時,提出用加權幾何平均值來計算路面使用性能綜合評價指標pqi ; ( 3 )提出了利用轉移概率檢查狀態的劃分和典型措施的合理性的新思想; ( 4 )在求解markov決策模型時,通常使用的方法是線性規劃法,本文闡述了另外兩種求解的方法:策略迭代法和整數規劃法。
