  1. The main results and academic contributions of the dissertation can be summarized as following : 1 ) for the difficulty to obtain the accurate analytical solution of the stress constraints around 3d cracks, detailed 3d fe analyses have been conducted to study the out - of - plane constraint factor tz around a straight through - thickness crack, a quarter - elliptical corner crack and a semi - elliptical crack embedded in an isotropic elastic plate subjected to uniform remote tension loading. the distributions of tz are minutely studied in the forward section of the cracks. strong 3d zones ( tz > 0 ) along the crack front were investigated despite the far field stress - free boundary conditions

    全文主要研究內容和學術貢獻如下: 1 .針對一般三維裂紋部場應力約束準確解析的困難,對均勻拉伸載荷作用下各向同性彈性板中穿透厚度中心裂紋、半橢圓面裂紋和1 / 4橢圓角裂紋進行了大量詳細的全場應力三維有限元分析,首次全面分析了非穿透裂紋部場三維響區范圍,給出了不同形狀三維裂紋前沿離面應力約束因子tz的數值解,並結合k場平面解給出了非穿透裂紋部應力場k - tz雙參數描述。
  2. The simulation results show that the power factor and efficiency of lim are much lower than that of rotary induction motor due to end effect and big air gap of lim. end effect force has a great influence on the thrust of lim. the performance of lim can be improved with the proper secondary structure, small air gap, big goodness factor or heavy load

    結果明:受邊效應及大氣隙響,線感應電機功率因數及效率較低;運行狀態下的邊效應力對電機推力有較大響;設計電機時選用合適的次級材料、減小氣隙、增大品質因數、增加負載都可提升電機的輸出性能,通過設計有效的控制演算法可使電機在額定滑差下具有較高的運行效率。
  3. The cause of vacuum degree formation under groundwater table is discussed in the paper. the testing results show that vacuum degree above the groundwater table is produced directly by pumping air, and that vacuum degree below groundwater table is produced mainly by dewatering and by escaping of sealed air from the end of flexible pipe. based on the bernoulli equation, the limit lowering of groundwater table is analyzed, which is about 5 ~ 7m. the effective influence depth of vacuum preloading has relationship with pvds depth and can be more than 10m

    對地下水位線以下的真空度成因進行了分析,結果明,地下水位線以下測到的真空度是由於測試軟管中水位下降或部分封存氣體從軟管末逃逸引起的,與地下水位線以上的真空度由抽氣接形成在成因上存在不同;根據伯努俐方程,對地下水位下降的極限深度進行了分析,得出真空預壓中地下水位的極限下降深度為5 7m ;對有效響深度的分析結果明,真空預壓的有效響深度與塑料排水板的打設深度具備一定關系,有效響深度可以超過10m 。
  4. At the extreme end of the spectrum there are those who believe that china s wto entry will be one more nail in the coffin, one more noose around the neck, for hong kong : that the diversion of business that will result from the now well advanced infrastructural development in china s coastal cities and the direct access provided through wto membership heralds the demise of hong kong s historical role as intermediary between china and the rest of the world

    至於對香港的響,則意見紛紜。最極的意見認為中國入世對香港來說將會是另一個催命符,香港的生意會轉流向基礎設施已發展良好的中國沿海城市而中國成為世貿組織成員后,外資可接進入內地市場,示香港作為中國與海外地方的中介渠道的歷史角色將會告一段落。
  5. With the input of a vibration acceleration history of subway train, a full dynamic analysis of soil - pile - structure is carried out. the propagation of vibration wave on the ground and vibration responses of the huge platform and the storied buildings are analyzed. some conclusions are drawn as follows : ( 1 ) with the increase of the distance to the vibration source, vibration intensity of the ground decreases ; ( 2 ) the vibration intensity of the ground in vertical direction is slightly larger than that in horizontal direction ; ( 3 ) with the increase of the distance to the vibration source, the situation that the vibration intensity of each building in horizontal direction is maximum at highest and lowest story whereas minimum at the middle story changes gradually to that decreasing with the height of building ; ( 4 ) in vertical direction, the vibration velocities and accelerations at the end points of each story of a building are the nominal identical, which indicates that the vertical vibration of them is unanimous ; ( 5 ) the vibration intensity in vertical direction of a building is larger than that in horizontal direction ; ( 6 ) increasing of the elasticity of track is an effective way to abate vibration of ground and buildings

    本文以北京地鐵八王墳車輛段地上超大結構(車輛段大平臺及其上的小區樓房)及其地基基礎為研究對象,在研究和分析有關資料的基礎上,用快速拉格朗日有限差分法軟體flac建立了二維數值分析模型,並以列車振動加速度時程作為模型輸入,進行了地基?樁基礎?地上結構的整體動力學分析,分析了地鐵列車運行產生的振動在地面的傳播規律及其對地上結構的響,得到了如下結論: ( 1 )隨著與地鐵線路距離的增大,地面的振動強度有減小的趨勢; ( 2 )地面豎方向的振動強度較之水平方向的略大; ( 3 )隨著與振源距離的增大,在水平方向上,地上各幢樓房的振動強度由底層和頂層的最大、中間層的最小逐漸過渡到沿樓層增高而減小; ( 4 )在豎方向上,每幢樓各層點的振動速度、加速度完全相同,明樓房各層在豎方向上的運動狀態一致; ( 5 )各幢樓房豎方向的振動強度比水平方向的大; ( 6 )增加軌道彈性是減輕地面和地上建築振動的有效途徑。
