中文拼音 [cuìxìngyándàn]
脆性巖石
英文
brittle rock-
So these karst series problems are lowness ability of making soils, distributing odds of surface water and groundwater, leakiness of fountain, alkalescence of circumstance, lowness of bio - diversity, rapidness converse succession of vegetation and fragility of soil character and entironment. and karst region produces many problems, e. g. rock desert, soil erosion and degeneration because of artificial influence and destruction
巖溶空間介質具有地上地下雙層結構，可溶巖造壤能力低，巖溶水空間分佈不均、地表地下水關系密切、水源易漏失，偏堿性環境、生物資源集聚程度低，植被逆向演替快、順向演替難，巖溶地質與生態環境十分脆弱，受到人為因素的影響和破壞，極易產生石漠化、土壤侵蝕與退化等一系列問題。A fact of great importance for geology is that brittle materials such as rocks tend to become ductile when subjected to large hydrostatic pressure.
地質水中一個十分主要的事實是：當受到很大水壓時，脆性材料如巖石等有變成延性材料的趨勢。Keywords : fractography, brittle material, failure mode, model rock
關鍵詞：裂形學、脆性材料、破裂模式、人工巖石。There are certain difficulties in studying the failure process of frangible materials such as concrete, rock, etc which are caused by dynamic loads such as collision, earthquake, exploding, etc by those current exited numerical methods like finite element method etc. so in order to solve such a problem we should introduce certain new numerical analysis method
現存的一些數值方法如有限元法等在研究混凝土、巖石等脆性材料在沖擊、爆破、地震等動荷載作用下的破壞過程問題中存在著一定的困難。因此，對於此類問題需要新的數值分析方法。Brittleness of rocks and brittleness indexes for describing rockburst proneness
巖石脆性及描述巖爆傾向的脆性系數Principle : it is adoping tattered dose to blend inner place the pouing perforate against water, utilizes such water action to come into being swelling the pressu ` re, by the rock, confuses soil forms piece and so on the brittleness substance distends to crack either cuts
原理：它是採用破碎劑與水混合灌入鉆孔中內，利用其水化作用產生膨脹壓力，將巖石、混泥土構件等脆性物體脹裂或切割。Influence of heterogeneity on macroscopical crack form of the brittle rock
細觀非均勻性對脆性巖石材料宏觀破壞形式的影響Plastic strain first starts from ambient of the porphyroblast, and then develops to rims of porphyroblast and gradually transfers to the centers of porphyroblasts. the brittle remains in the central parts of porphyroblasts come to be decreased through the plastic deformation development, which is accordance with the banding of intensity in many mylonitization zones on wild occurrences and observation in the fabrics of mylonitization rocks under microscope
長石眼球構造的形成主要是由長石與石英的韌性差決定的，塑性變形首先從斑晶的周圍部分開始，逐漸向斑晶發展，脆性殘斑核不斷減小，這與剪切帶內糜棱巖化強度分帶相一致。Physical mechanism of dependence of material strength on strain rate for rock - like material
巖石等脆性材料動力強度依賴應變率的物理機制Study on model of damage and flow coupling in brittle rock failure process
脆性巖石破裂過程損傷與滲流耦合數值模型研究Prediction of quasi - brittle fracture of concrete and rock structures using laboratory - sized specimens
用試驗室尺寸的試樣預測混凝土及巖石結構的準脆性斷裂Centrifuge modeling of failures of cohesive soil slopes
