The frozen damage of slab - foundation of channel irrigation structures in the northeast of china is the most serious and includes the general characteristics of frozen damage of the channel irrigation structures
我國凍土分布面積極為廣闊，雖然東北地區渠系水工建筑物的板基凍害最為嚴重，但也是其它地區的共性問題。

Through a systematic research , the author enter to provide the theoretical basis for selecting reasonable index of normal frozen - heave forces and the technology for preventing and controlpng frozen damage
通過系統研究，渴望為季節凍土區涵閘類水工建筑物基礎板的設計部門提供法向凍脹力值的設計指標，以便做到基礎的合理淺埋和進行抗凍脹設計。

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 beeen nthpc and ordinary concrete , and therefore durabipty 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 apppcation need , and this are o emphasized and difficult problems , as for nthpc ; by means of mechanism analysis about deicing - agent ingredient and anti - freezing at early period , adopting posite technique routine of mineral addition + anti - freezing element + water - reducer4 - air - entraining + anti - erosion of steel ponent etc , based on orthogonal experimental approach , fd - 1 posite functional admixtu re was manufactured , which has more property and orientation on qing - zang railway
負溫混凝土由于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，采用礦物外加劑+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 ；并在此基礎上配制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。

The patibipty and harmony among workabipty , mechanical grade and durabipty are optimized , with the ground of adjusting position and dosage of fd - 1 ; after analyzing anti - freezing damage mechanism , it is concluded that temperature is main factor , which affects structure and property of concrete . after o processes of temperature - elevation of hydration heat and temperature - descent of cold - environment , there is original damage in concrete and its existence leads to temperature fields , as results in temperature damage on transition phase > aggregate and cement mortar of concrete
通過對負溫混凝土早期防凍分析研究認為，環境溫度對混凝土的結構形成及其性能的影響十分突出，水泥水化溫升和環境散熱降溫兩個過程導致混凝土結構內部產生不均勻溫度場，對過渡相、水泥砂漿以及骨料都能產生不同程度的溫度損傷，產生內部溫差應力裂紋，初始損傷也是不可避免的。

Abstract : based on the fundamental principle of hypothesis strain equivalence , ias investigated a physical concept of high strength concrete at minus temperature ( hscmt ) freezing damage parameter , the elastic modulus of frost concrete with anti freeziug admixture and without antifreezing admixture built and it was analyzed their variate process and the condition adaptated . it is purpose to judge hscmt frost failure process
文摘:從應變等效性假說的基本原理出發，研究了負溫混凝土凍結損傷參數? ?彈性模量法中受凍后測試的損傷混凝土彈性模量的物理概念，從而分析了摻防凍劑混凝土及不摻防凍劑混凝土受凍后的彈性模量變化過程及其選用該參數的適應性條件，為判斷負溫高強混凝土材料凍結失效過程提供保證。
