凍裂縫 的英文怎麼說
中文拼音 [dònglièféng]
凍裂縫
英文
frost fracture-
Results showed that the temperature distribution of the traditional embankment was asymmetrical ; the asymmetrical status was changed after ripped - rock revetment was installed and the soil under the ripped - rock was cooled obviously ; the ripped - rock revetment could cool embankment and adjust the temperature difference between the north - facing slope and the south - facing slope ; the ripped - rock revetment was an available technique to protect embankment from thawing settlement and longitudinal cracks in permafrost regions
結果表明：普通路基的陰陽坡兩側溫度分佈極不對稱；鋪設拋石護坡后，這種狀況得到了很大改善，並且拋石護坡下土體溫度明顯降低；拋石護坡能夠降低路基溫度和調節路基陰陽坡的溫度差異；拋石護坡是多年凍土區防治路基融沉和縱向裂縫病害的一種可行措施。The longitudinal cracks have become the main subgrade distress type in the permafrost regions, and there is not a effective solution now
縱向裂縫目前已成為多年凍土地區路基病害的主要類型之一，目前還沒有一種有效的解決方法。Seismic fracture, fault fracture and permafrost fracture all gave negative effects on engineering construction and formed geological hazards at many localities along the golmud - lhasa highway and railway ice fractures formed in freezing rivers and lakes and on the top of pingos have not shown any hazard effect on engineering constructions up to the present
地震破裂、斷層裂縫和凍土裂縫對青藏公路、青藏鐵路及沿線工程安全具有不良影響，這些地裂縫切割錯斷路基，形成路面破裂和路基滑塌，產生顯著的災害效應。Through surveying and analysis by synthesis of the environment of qingzang highway and the damage condition of the highway ' s base course, this paper take experiments of the key performances of the atsm, discusses the standards of control indexes of atsm for base courses in perennially frozen zone. by all the results of such experiments, a conclusion is obtained that the strength and all the pavement performances properties of the atsm are good enough to be used to build the base course of highway in perennially frozen soil zone
寒區半剛性基層強度較難形成，而形成板體的基層又大多出現嚴重的反射裂縫，影響了使用性能，因此，本文通過調查與分析青藏公路的自然條件和路面基層及面層的損壞狀況，對基層瀝青穩定碎石的強度、低溫抗裂、疲勞以及抗凍等各項路用性能進行了試驗研究，探討了多年凍土地區基層混合料的關鍵路用性能的各項指標。Permafrost fracture and ice fracture are both the result of freezing expansion without evident relation to tectonic deformation and regional structures
凍土裂縫和冰裂縫屬外營力成因地裂縫，是凍土與冰層不均勻融凍變形的重要表現形式。Fault fracture zones often form in active fault zones and appear as long extension with stable trending, they are jointly controlled by active faulting, underground water concentration and freezing expansion
斷層裂縫沿斷層破碎帶定向分佈，產狀穩定，成群產出，與斷層活動、地下水運移、不均勻凍脹存在密切的關系，是構造變形與融凍變形聯合、內外動力耦合產生的復合成因地裂縫。Mechanism and prevention of deformation cracks of embankments in the permafrost region along qinghai - xizang railway
青藏鐵路多年凍土區路基變形裂縫發生機理及其防治This is especially a problem in extreme climates where water can get into the cracks between supports, freeze and expand and cause a huge amount of damage
特別是在極端氣溫中，水會滲進橋墩之間裂縫，冷凍擴大並造成巨大的傷害。 」分享友人
