過渡加載
英文
tra ient loading-
Pile - net composite foundation has some merit in building up the reinforcement of composite foundation simultaneous in vertical and horizontal directions, in enhancing the bearing capacity of foundation soil, and minishing the non - uniform settlement, especially controlling the phenomenon of vehicle dumpping on bridge head in the foundation treatment of transitional segments which is proved by practice
摘要實踐證明，樁網復合地基同時具備豎向增強體復合地基與水平向增強體復合地基的加固優點，能很好地提高地基土體承載力，減小不均勻沉降，特別是橋頭過渡段地基處理中能有效控制「橋頭跳車」現象的產生。Then, taking into account the effect of the compression of the approach roadway and the differential slope of the bridge slab, the author analyzes the dynamic response of man - vehicle - road system when the vehicle approaches and leaves the bridge by means of laplace transform, the curve of man ' s acceleration versus time, the vertical force between the vehicle and road versus time, the man ' s maximum transient vibration value and the maximum force between the vehicle and road are got, and the program about the calculating progress above are edited. based on the analysis above, the influence on the maximum transient vibration value of some parameters about the vehicle and road such as the movement direction and speed and weight of the vehicle, the differential slope of the bridge slab and the length of the approach slab, are studied, and some conclusion are given
分上橋和下橋兩種情況，考慮車路耦合和橋面沉降坡差的影響，對車輛通過設和不設搭板的路橋過渡段時「人?車?路」系統的相互作用用拉普拉斯變換法進行了動力響應分析，得到了人的加速度及路面對車的垂直作用力隨時間的變化曲線、人的加速度最大瞬態振動值和路面對車的最大作用力，分析了車輛的行進方向、速度和載重，橋面沉降坡差和搭板長度等車和路各參數對計算結果的影響，並編制了相應的計算程序。The results indicate that this method can minish settlement largely, decrease level thrusts on bridge abutment, make the settlements transition, improve the bearing capacity of foundation soil and its economic benefits are notable. the results of field test show that low intensity piles can put into widely use in soft foundation of express way
研究結果表明，採用低強度樁復合地基加固橋頭軟基時，可以採用變樁長、變間距的設計思想，使沉降逐漸過渡，減輕橋頭跳車的危害，並且還可以減小沉降和深層土體水平位移，減小對橋臺及其樁基的水平推力，提高地基承載力。Notification indicates that an object is making the transition from the running state to the loaded state, so its container can take appropriate measures to ensure orderly shutdown
通知指示對象正在從運行狀態向加載狀態過渡，所以它的容器可以採取相應的措施來確保實現有序關閉。Transient layer approach was used in finite element method to simulate the temperature difference between the loading liquid and the model internal wall surface, and the results of calculation and test are accordant
採用過渡層模擬加載液體與模型內表面的溫差，進行有限元計算，計算結果與試驗結果相符。分享友人
