And the calculated results closely coincide with experimental results . furthermore , the paper , through applying the improved algorithm to the load - deflection curve and secondary load , also the calculated curves closely coincided with experimental results ( showed as chart 3 . 17 - 3 . 20 ) 本文還將改進的算法運用于粘貼加固受彎構件的荷載?撓度曲線和二次受力問題的計算中,得出與試驗結果吻合較好的計算曲線(圖3 . 17 3 . 20 ) 。
Adopting the deformation harmony theory , the numeric calculation of the curve of load versus settlement is made . the fitting results between the calculated curve of load - settlement and the measured one of piles with different construction process are illustrated . hence , under the condition of few or no static load test data , the performance of bearing capacity of single bored pile in loess may be predicted utilizing indexes of shear wave velocity , static cone penetration test and modification coefficient of depth , so it is remarkable to reduce the blindness of preliminary design of pile 通過室內(nèi)試驗及原位測試指標進行理論計算與現(xiàn)場實測值的對比,筆者引入了施工工藝修正系數(shù)k _ ( c1 )和k _ ( c2 )及深度修正系數(shù),使理論計算值與現(xiàn)場實測值具有良好的一致性,進而通過變形協(xié)調理論對荷載?沉降曲線進行數(shù)值計算,并用不同施工工藝的實例說明了理論計算荷載?沉降曲線與實測荷載?沉降曲線的擬合效果,從而達到可在不做靜載荷試驗或少做靜載荷試驗的情況下通過剪切波速和靜力觸探試驗指標以及施工工藝修正系數(shù)等預測黃土地基中鉆孔灌注樁承載性狀,這對于工程初步設計中減少設計的盲目性具有十分重要的現(xiàn)實意義。
Comparing with the approached curve and the calculated curve , the credibility of numerical simulation result and the feasibility of predicting the ground settlement through numerical simulation are verified . so it can be used to analyze the structure settlement due to the tunnel construction with shield 本文利用數(shù)值模擬計算得到的指定斷面地表沉降與實際測量結果基本吻合,這充分說明只要建立合理的數(shù)值模型,采用合理的計算參數(shù),數(shù)值模擬是研究盾構施工力學過程的有效工具。
We presents a detailed studied of the linewidth of parametric light in clbo - opo caused by the linewidth of pumping beam , off axis phase matching , divergence angle of pumping , time above threshold , high gain coefficient of nlo crystal , fluctuate of cavitylength , spontaneous radiation , according to the momentum and energy conversion laws , and the sellmeier equations of the clbo , we calculated curves of the type - i and type - ii compared with the bbo ' s 根據(jù)能量動量守恒關系和clbo的色散方程,詳細分析了由于泵浦光的線寬、泵浦光偏軸泵浦、泵浦光的發(fā)散角、泵浦光功率超過參量光振蕩閾值一定倍數(shù)、高增益系數(shù)、有效腔長波動以及自發(fā)輻射引起的參量光線寬,并得到了與bbo晶體在類、類相位匹配下比較的理論曲線。
