    本文依託國家自然科學基金重點項目「江口濱岸潮灘復雜境條件下物質研究」 (批準號: 40131020 ) ,選擇了江口崇明東灘敞開型潮灘為研究對象,設置典型斷面,在平靜天氣條件下,實測了文、地球化學要素,獲得了位、流向、流速、 tn及tp等指標6000多個實測數據,著重對江口潮灘動力過、 tn和tp動力輸移過進行研究。
  2. This paper unfolds engineering disposition and theoretical research of negative temperature high performance concrete ( nthpc ) with the damage of many factors motivation, the project background based on qing - zang railway engineering, which is one of four - emphasized engineering during the tenth five - plan. due to the difference of environment of construction and service between nthpc and ordinary concrete, and therefore durability of nthpc is required to higher level. at a first, nthpc must avoid frozen damage at early age and possess anti - freezing property at later period, in order to meet engineering practicable application need, and this are two emphasized and difficult problems, as for nthpc ; by means of mechanism analysis about deicing - agent ingredient and anti - freezing at early period, adopting composite technique routine of mineral addition + anti - freezing element + water - reducer4 - air - entraining + anti - erosion of steel component etc, based on orthogonal experimental approach, fd - 1 composite functional admixtu re was manufactured, which has more property and orientation on qing - zang railway

    負溫混凝土由於和普通混凝土在施工境及服役境上存在差異,因此表現為比普通混凝土更為較高耐久性要求;負溫混凝土首先要避免早期凍害以及具備期抗凍性能,才能夠滿足工實際應用要求,這也是負溫混凝土必須解決兩大技術關鍵;通過對目前常用防凍劑組分作用機理分析研究及混凝土早期防凍機理探討,採用礦物外加劑+防凍組分+高效減劑+引氣+阻銹組分功能復合技術路線,通過正交試驗設計復配了適應青藏鐵路工要求專用多功能復合型外加劑fd - 1 ;並在此基礎上配製不同等級負溫高性能混凝土,開展一系列包括硫酸鹽侵蝕、氯離子滲透、抗凍融、收縮及耐磨性等耐久性能研究;通過對fd - 1組分和摻量調整,優化負溫混凝土在施工特性、力學指標和耐久性三個方面兼容、協調性。
