  1. 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環境及服役環境上存在的差異，因此表現為比普通混凝土更為較高的耐久性要求；負溫混凝土首先要避免早期的凍害以及具備長期抗凍性能，才能夠滿足工程實際應用的要求，這也是負溫混凝土必須解決的兩大技術關鍵；通過對目前常用防凍劑組分作用機理的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+高效減水劑+引氣+阻銹組分功能復合的技術路線，通過正交試驗設計復配了適應青藏鐵路工程要求的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、抗凍融循環、收縮及耐磨性等耐久性能研究；通過對fd - 1組分和摻量的調整，優化負溫混凝土在施工特性、力學指標和耐久性三個方面的兼容、協調性。
  2. According to the basic equation for water flow in subgrade soil, based on the basic soil properties of compacted loess, the redistribution of soil moisture and the soil water - migrate parameters are studied

    摘要基於黃土路基壓實後土體的基本性質，根據路基土中水分運動的基本方程，通過室內一維土柱入滲試驗，得到不同壓實度的黃土濕潤鋒濕度與平均濕度、水分入滲速率的關系曲線。
  3. The field of water distribution is obtained by finite difference method, then it is transformed into weight field and strength field or the field of suction distribution. the safety factor of slope during the infiltration time is calculated by slice method according to the actual weigh field and strength field

    在有限差分法求得土坡水分分佈的基礎上，提出了用條分法計算土坡在降雨入滲各個時刻安全系數的思路：把水分分佈場轉化為邊坡的基質吸力分佈場（強度場）和重量場，用邊坡的實際重量場和強度場來進行安全系數的計算。
  4. Secondly, in combination with basic physical experimentation of the henan item “ study on embankment settlement mechanism and development rule for highway in the silt soil region ”, the mechanics speciality of silty soil is completely cognized and realized, through the laboratory experimentation of three kind of classical silty soil in puyang city. the experimentation include laboratory physical mechanism test, static compaction test, direct shear test, permeability test. and also analysis the influence of water content on soil ’ s shear strength, permeability and other mechanism character

    其次，結合河南項目「粉砂土地區高速公路路基沉降機理及其發展規律研究」課題的基本物理試驗部分，通過對濮陽市三種典型的粉質土的室內物性力學性質試驗、標準擊實試驗、直接剪切試驗、滲透試驗等一系列試驗研究，對粉質土的各力學特性進行全面系統的認識和了解，分析了含水量對粉質土的抗剪強度、滲透性等力學性質的影響。
