段頭剪
英文
decapitating scissors-
These landslides go with fluidization peculiarity different degree in course of their motion, and their speed and distance increase several times because of the fiuidization, thereby the disaster area greatly broaden. on the base of above, the paper studies systematically the fluidization of large high - speed rockslides in all its aspects : analyzed the aerodynamic effect in the short - range on the base of the wind turmel experiment, studied the effect of falling into pieces when landslides collides mountain ; studied the accelerating effect through high - speed collide experiment of landslides model ; and the paper reappear the overall process including set - out, collide in the short range, debris flow in the long - range of touzhai large landslide via distinct element method ( dem ), studied the flow law and equation of different type of debris flow resulted from large landslide. as a sample to apply, the paper analyzed fluidization mechanism of touzhai landslide
基於這一點，本文對大型高速巖質滑坡的流體化現象進行了全面而系統的研究：通過風洞模型實驗，研究了大型高速滑坡凌空飛行階段的空氣動力學效應，研究了飛行中滑坡巖體在與途中不動山體發塵碰撞時的解體破碎效應，通過滑坡巖體高速碰撞模型實驗研究了滑坡巖體解體破碎後部分巖體的加速運動效應，並應用離散單元法再現了雲南頭寨溝大型滑坡啟動高速、近程碰撞、遠程碎屑流運動的全過程，研究了巖體解體破碎后形成不同類型碎屑流的運動規律及運動方程，並對頭寨滑坡流體化運動機理進行了實例分析，取得了以下主要結論和成果： （ 1 ）對于大型高速滑坡，大多在啟程活動階段已獲得了高速，這使得這類滑坡在其離開剪出口之後以凌空飛行的形式向前運動，在其飛行過程中，滑坡巖體與空氣強烈作用，並產生空氣動力學效應，滑坡巖體在因碰撞而產生的解體破碎效應及部分巖體的加速運動效應的作用下，在遠程活動階段，以高速碎屑流的形式向前運動。One of these splicing signals sits at the beginning of the intron and is called the 5 ' ( five - prime ) splice site ; the others, located at the end of the intron, are known as the branch site, the polypyrimidine tract and, finally, the 3 ' ( three - prime ) splice site
其中一段位在插入子的起頭，有一個剪接信號序列，標明5 '端剪接位；插入子的尾端有其他的信號：分支點、多嘧啶區，最後則是3 '端剪接位。Postgraduate : pu liangtao supervisor : professor shang shouing senior engineer huang gang the research on influence of the post - casting section of continuous rigid bridge suffered vibration of train travelling is preseated in this thesis according to related project. based on theorize analysis, expriments of material properties and members under deformed vibration, verification of isolating and reducing vibration in building as well as construction technology and quality control, the effect of post - casting section suffered deformed vibration is studied thoroughly. through the analysis of 28 tests of shear strength with post - casting section under deformed vibration, the related laws are deduced. and the analysis of finite element method, the studies of quality control and construction technology are also completed
通過現場測試、模型和試塊的模擬振動成型試驗、加載破壞試驗、理論分析、現場減振隔振試驗、施工工藝和質量控制等一系列全面、系統的研究工作，認真、深入地研究了現澆混凝土受火車行駛振動的影響，特別是在約束構件后澆濕接頭區段內現澆混凝土受火車行駛振動影響研究方面作出了開創性的工作，完成了振動使濕接頭區段受到彎曲變形影響條件下的構件模擬振動試驗、抗剪強度試驗。
