1.路基;地基
1.the bed of ground on which the foundations of a road, railroad, or building are laid
1.The surface deflection has linear change with base thickness and curve changes with subgrade resilient modulus and base resilient modulus.
表面弯沉随基层厚度呈线性变化，随土基回弹模量和基层回弹模量呈曲线变化。
2.Also, as the cyclic loading effects of the train to the subgrade, the improved subgrade needs to possess quality dynamic characteristics.
由于列车对路基的循环荷载作用，因此改良后的路基还要有优良的动力学特性。
3.But for large subgrade depth, the effect of reinforcement did not significantly increased with the increase of subgrade depth.
但在软土层厚度较大时，加筋效果随软土深度增加提高较少。
4.Dynamic stress is distributed as saddle along the lateral direction of subgrade surface. Dynamic stress along the depth declines sharply.
路基面动应力在横向呈马鞍分布，动应力沿深度方向衰减较快。
5.In subgrade construction of railway engineering, the total cost of construction materials costs of more than 60%.
铁路工程路基施工中，材料费用占总施工费用的60%以上。
6.Now, reinforced soils have been used widely in road, railway subgrade, slope, retaining wall, bank protection and so on.
目前，加筋土已广泛应用于公路、铁路路基、边坡、挡土墙以及河岸等工程。
7.The results show that the geocell reinforcement can reduce the settlement of the subgrade, but a size effect is existed.
结果表明，格室体的设置可有效地减小路基沉降，但也存在着尺寸效应；
8.Without a strong and stable subgrade there is no stable pavement.
没有坚固、稳定的路基就没有稳固的路面。
9.The increase of axle load and track regularity are the key factors affecting the dynamic stress of subgrade as the speed of train increases.
列车提速时，轴重增加和轨道不平顺对路基动应力影响最大。
10.Foundation soil coefficient of subgrade reaction is an important computation parameter in geotechnical engineering.
地基土基床系数是岩土工程中一个非常重要的参数。
