集料破裂 的英文怎麼說
中文拼音 [jíliàopòliè]
集料破裂
英文
aggregate fracture-
Failure probability of coarse aggregates ( pfca ) could be a sample index durability evaluation of concrete in compressive strength test, where pfca was the ratio of number of total particles to which of the broken ones of coarse aggregates in the failed faces of a concrete specimen
混凝土抗壓試驗中，粗集料破碎率p _ （ fca ）可以作為混凝土耐久性的一個簡要評價指標，其定義為試件斷裂面上破碎的粗集料顆粒數與暴露的粗集料顆粒總數之比。There is an old saying in our field - " no dam is not crackable ". the crack is mainly because of the bad dilation after " alkali - aggregate reaction ", the temperature traverse inside and outside the concrete with the happening of heat evolution and the shrink of volume due to the cooling of concrete
水電行業有句「無壩不裂」的俗話，產生裂縫的原因主要有「堿集料反應」造成的破壞性膨脹，水泥水化過程中放出的熱量出現的混凝土內外溫度梯度和水泥石硬化後由於後期降溫發生的體積收縮等造成。Abstract : based on the data obtained from field observations and deformation monitoring, this paper deals with the deformation and failure of a double - decked slope composed of soft rock strata in its lower part and hard - brittle rock strata in its upper part. it is demonstrated that the deformation of this kind of slopes is always initiated by the non - homogeneous rheological compression of the lower soft rock strata, leading to the tension fracture and toppling of the upper hard rock strata, and at last the sliding of the whole deformed body will be caused by the shear failure along the stress - concentration zone in the lower soft rock mass under the actions of the gravitational loading and infiltration water
文摘:以現場考察和變形監測資料為依據，探討一個下部有軟弱基座，上部為硬脆性坡體的「二元結構」邊坡的變形破壞問題，揭示這類邊坡的變形總是以下部軟弱巖體的不均勻壓縮流變為先導，進而引起上部硬脆性坡體的拉裂與傾倒，最終通過滲入水的作用，使下部承載狀況已進一步惡化了的軟弱巖體，沿剪應力集中帶發生剪切破壞而導致整個變形坡體的下滑。According to the characteristic transformation of the eme in the process of its deformation, the stress concentration belt engendered by the coal wedge of the protective coat can be ascertained and the electromagnetic radiation measured result is consistence with the calculation result of the site survey materials
根據煤體變形破裂過程中產生的電磁輻射信號特徵變化，確定了保護層采空區煤柱產生的應力集中帶，電磁輻射測定結果與現場勘測資料計算結果相吻合。It was analyzed by means of metallographical examination, chemical composition analysis and inclusion testing, the results show that the fracture was mainly caused by no - metallic inclusion
通過對層裂坯料進行宏、微觀檢驗、化學成分和夾雜物分析，認為大顆粒硫化物夾雜及其富集破壞了基體的連續性，是鐓制過程中產生裂紋的主要原因。分享友人
