Modified cambridge model and its simulation test 對修正劍橋模型的認識及試驗模擬
Modified cambridge model 修正劍橋模型
For example , the famous modified cambridge model can display the elastic - plastic property of soil , but it can not display the rheological behavior of soil 比如著名的修正劍橋模型能較好的反映土體的彈塑性,但不能考慮流變特性。
According to the functionary times of transportation times and spatial location between pipelines and roads , three kinds of transportation load models are put forward , i . e . long - term evenly distributed load , movable invariable load and stable simple harmonic load . two common foundation models , linear elastic model and modified cambridge model are analyzed , and the former is selected as the model for soft soil in this paper . considering the application actuality and foreground of steel , steel pipeline is adopted as research object 根據(jù)交通荷載的作用次數(shù)以及管道與道路的空間位置,提出了三種交通荷載模型,即長期均布荷載、移動恒載和穩(wěn)態(tài)簡諧荷載;分析了常用的兩種地基模型?線彈性模型和修正劍橋模型,并選擇了線彈性模型作為本文的地基模型;考慮到鋼管的應用現(xiàn)狀和前景,選擇鋼管作為研究對象;從法向和切向?qū)?土相互作用模型進行了探討。
