  1. By the large quantity of indoor and field soil mechanics test, this paper investigated physics and mechanics property of xigeda stratum and xigeda compounding filling, profoundly and systematically studied on shearing strength, cbr ( including indoor cbr and field cbr ) and intensity feature of xigeda compounding filling. the new achievement and cognition as follows : ( 1 ) cbr value is decided by moisture content and mudstone content of xigeda compounding filling. the filling material can satisfy minimum intensity standard of express highway when mudstone content is less than some fixed value, ( 2 ) this paper established field cbr standard value which can synthetically evaluate the filling material nature and field compaction degree. ( 3 ) the optimal compacting mean of xigeda compounding filling is hard oscillation first and weak oscillation later, not traditional way which is weak oscillation first and hard oscillation later. ( 4 ) this paper put forward the conception of optimum moisture content in construction different from optimum moisture content of indoor impaction

    本文以昔格達填料強度特徵為研究對象，通過大量的室內及現場試驗，從昔格達地層巖組的物理力學性質、昔格達填料的物理性質入手，對昔格達填料的抗剪強度、室內承載比及現場承載比特徵進行了較系統地研究，獲得了如下認識及進展：昔格達混合填料承載比值受填料含水量及其中泥巖含量的影響，當泥巖含量小於一定值時，昔格達混合填料具有較高的承載比值，能夠滿足高速公路對填料的最低強度要求；建立了綜合評判昔格達填料性能及現場壓實效果的現場承載比（ cbr ）標準；對于昔格達填料而言，最佳的碾壓方式為先強振后弱振而不是傳統的先弱振后強振；提出了與室內擊實最優含水量相區別的施工最佳含水量的概念。
  2. Some respects of self - compacting high - strength concrete ( schsc ) made of fujian province ' s local material have been studied in this thesis as follows : 1. studies on microstructure of the schsc. three different mixed schsc and one normal high - strength concrete ( nhsc ) were observed by the scanning electron microscope at different sites and different ages of 1 day, 3 days, 7 days, 28 days and 60 days. from the test, the effects due to no vibrating and admixture on the microstructure of schsc were studied

    通過四組強度等級相當，分別為普通混凝土、兩組不摻膨脹劑的自密實混凝土（其粉煤灰的摻量不同）和摻有膨脹劑的自密實混凝土，在同一養護齡期的條件下（ 1天、 3天、 7天、 28天和60天） ，分別選擇粗骨料過渡區、細骨料過渡區、水泥石和砂坑作為觀測點，採用sem進行細觀掃描對比實驗，以研究自密實混凝土因免振搗的特性及摻合料對其骨料界面和水泥石結構的影響。
  3. In this paper, the so preparing self - compacting concrete with low and middle strength using super fine mountain sand artifical sand and phosphorus slag is studied systemically. through the study the influence of the shape, the proportion of the dust and the grade of sand to the workability and the mechanical property of self - compacting concrete, it is found that super fine mountain sand artifical sand are not suit to prepare low and middle strength self - compacting concrete, but when they are combined and the additive and assistant band material are used, c20 - c40 high performance self - compacting concrete is prepared ; the corresponding additive is developed to solve the delamination caused by the low proportion of banding material ; the evaluating system for the workability of low and middle strength self - compacting concrete is built ; the controlling method for production, construction and curing was set up. and the result of the research is applied into several projects

    通過分析特細山砂和機制砂的顆粒形態、粉末含量、顆粒級配等特性對自密實混凝土的工作性能和力學性能的影響，發現特細山砂、機制砂不宜單獨用於配製中低強度等級自密實混凝土，宜將特細山砂和機制砂進行合理復配，並選擇合適的外加劑和礦物摻合料，優化配合比設計，可生產c20 c40中低強度等級自密實高性能混凝土；研製開發出了具有高效減水、保塑、抗離析功能的外加劑，有效解決了中低強度等級自密實混凝土由於膠凝材料用量少而出現的離析、泌水問題；應用正交設計方法，對因素和水平進行合理選擇，確定了生產中低等級自密實混凝土的最優配合比；建立了中低強度等級自密實混凝土的工作性評價體系；提出了生產、施工及養護的質量控制技術方法。
