Based on the analysis of the lateral acceleration data of vehicles measured in shanghai metro lin, this paper suggests that the lateral oscillation force of the vehicles shall choose 10 % of the vertical load on a single wheel
摘要根據鐵路車輛及上海軌道交通3號線上實測車輛橫向加速度值，建議橫向搖擺力取軸重的10 % ，按目前承軌合構造，車輛偶然脫軌后可能橫向偏移左右各1 . 75m 。It was shown that the maximum displacement occurred on the tunnel axis when one tunnel was excavated, while the maximum value happened near the shallow tunnel and between the area of two tunnels when two adjacent tunnels were excavated at the same time
分析結果表明：單條隧道開挖引起的地表最大沉降值出現在隧道軸線的正上方，而兩左右或上下相鄰隧道開挖的地表及土層內部的最大沉降值則出現在兩隧道的縱軸線之間，且偏向上方埋深較淺的隧道。The results show that there are two centers of occurrence of llsw respectively in dong bei and jiang nan ; the regional torrential rain over the yangtze river basin is closely associated with llsw during the major periods of heavy rainfall ; the diurnal variation of the number of occurrence in the middle and low reaches of the yangtze river is the strongest in china there are some significant differences between llj and nallsw in positive season, spatial variation, diurnal variation and field of pressure. by the way, the important effect of inertial stability on heavy rainfall with both low level south - westerly jet and high level northerly strong flow is analyzed theoretically. the results show that the existence of the maximum of inertial stability in the left font of the low level jet is favor of the accumulation of the moist thermal energy, and conditional symmetric instability or convective instability can be expected in this region
另外，慣性穩定性的作用以往不受重視，本文通過對西南低空急流左前方和高空偏北大風軸右後方的慣性穩定性和對稱穩定性的理論分析和實例計算，表明慣性穩定性在伴有高低空急流的暴雨中有重要意義，揭示了梅雨暴雨的一種新的高低空急流耦合機制：低空急流左前方慣性穩定度大值區的存在，有利於低層濕熱能量的積累，使低層傾斜對流的不穩定發展更多期望于條件性對稱不穩定或對流不穩定；高空偏北大風軸（西風急流）的存在，是其右後方（右側）出現對稱不穩定的有利條件，高空相對容易出現干對稱不穩定；慣性穩定性的作用，使低層的傾斜對流更偏向於垂直方向，有利於對流發展，使高層的傾斜對流更偏向於水平方向，有利於高層輻散。( 2 ) with f varying, there exists a number fr which is about - 1 ( curvature, torsion and dean number have little influence on fr ), when f > fr, the maximum of the axial velocity is near the outside bent and the friction factor ratio increases with f increasing ; when f < fr, the maximum is near the inner side bent and the ratio increases with f decreasing ; when f = fr, the distributions of the axial velocity are similar to those of poiseuille flow and the friction ratio is about 1
（ 2 ）當f變化時，存在確定的數值fr （ fr在- 1左右。曲率、撓率和dean數對fr的影響很小） ，當f fr時，軸向速度最大值偏向外側，摩擦系數比隨f增大而增大；當f fr時，軸向速度最大值偏向內側，摩擦系數比隨f減小而增大；當f = fr時，軸向速度的分佈和poiseuille流近似相同，摩擦系數比約為1 。分享友人
