    本文在重慶市某高速公合同了現場預裂爆破試驗的基礎上,研究了炮眼直徑、不耦合系數、炮孔、炮孔排、藥卷直徑、單孔藥量和線裝藥密度、裝填結構、起爆方式等爆破參數與爆破效果之的聯系,以及如何在給定的地質條件下調整爆破參數獲得最佳的爆破效果。
  2. 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地上超大結構(車輛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,了地基?樁基礎?地上結構的整體動力學分析,分析了地鐵列車運產生的振動在地面的傳播規律及其對地上結構的影響,得到了如下結論: ( 1 )隨著與地鐵線離的增大,地面的振動強度有減小的趨勢; ( 2 )地面豎直方向的振動強度較之水平方向的略大; ( 3 )隨著與振源離的增大,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、中層的最小逐漸過渡到沿樓層增高而減小; ( 4 )在豎直方向上,每幢樓各層端點的振動速度、加速度完全相同,表明樓房各層在豎直方向上的運動狀態一致; ( 5 )各幢樓房豎直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。
