凍土研究所 的英文怎麼說
中文拼音 [dòngtǔyánjiūsuǒ]
凍土研究所
英文
institute of cryopedology-
The concrete used in testing bridge is monitored and some performance at definite age including compressive strength, splitting fensile strength, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure by mercury porosimetry are tested. these performances are compared with that of concrete which designed by traditional method. the results show that mechanical properties of concrete designed by high durability concrete proportion and traditional method meet require ment at any age, however, frost resistance, scaling frost resistance, chloride ion diffusion coefficient ( dcl - ), resistance of carbonization and pore structure of the former are better than the latter, so high durability concrete is economic benefit
對試驗橋用混凝土的質量進行監控，並成型試件測量所需齡期內的抗壓強度、劈裂強度與抗凍融、抗鹽凍、氯離子擴散系數（ dcl - ） 、抗碳化等耐久性能指標及孔結構，並與傳統混凝土進行對比研究，結果表明:高耐久性混凝土及按傳統配合比設計的混凝土的力學性能均能滿足相應齡期的要求，但前者的抗凍融性能、抗鹽凍性能、抗碳化性能、 dcl -和孔結構明顯優於後者，並具有明顯的社會經濟效益。So analyzing the unique environment the highways there faces and researching the performance of asphalt mixes base course, and to imply a complete atsm ( asphalt treated stones mixes ) design method for base is an important question of our country ' s construction in wide perennially frozen soil zone
目前我國瀝青穩定基層使用較少，在多年凍土地區更是空白，所以分析多年凍土地區公路所面臨的特殊自然環境，研究瀝青穩定碎石基層的路用特性，提出瀝青穩定碎石混合料的設計方法是我國廣大多年凍土地區公路建設的一個重要課題之一。For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。Effects of frozen soil layer and radiant damp of foundation soil on site earthquake responses are studied in detail. the seismic wave that is prerequisite at the seismic responses calculation of structure is obtained by using back analysis
研究了凍土層的存在、地基輻射阻尼等因素對場地地震反應的影響以及通過反演計算得到結構地震反應分析時所需要的地震波。However, under the different conditions of climate, hydrogeology and engineering geology, all of above - mentioned steps are n ' t reliable in technology and reasonable in economy. aiming at the frozen disaster of roadbed at special frozen earth area, it is necessary for us to make deep - going study on the steps about roadbed against frozen disaster
但因氣候條件、工程地質、水文地質條件等方面的不同，對于特定的凍土區，上述所有的工程措施不都是技術可靠和經濟合理的，因此，針對特定凍土區的路基凍害問題，有必要對典型的路基抗凍害措施的有效性作進一步的研究。分享友人
