| 摘 要： | 京台高速公路K1040＋000~1047＋400段于2010年底开工扩建。在某高速公路扩建工程中，老路填土的受压沉降已基本完成，为控制拼宽部分路基的变形沉降，确保行车的舒适性，通过分析计算和有限元模拟，对开挖台阶的尺寸进行了优化设计。设计中采取了提高压实度、清坡、削坡、挖台阶、设置土工织物等措施，保证了拼宽路堤的质量。

| Abstract: | K1040 ＋ 000 - 1047 ＋400 of Jingtai expressway started to expand at the end of 2010. Old filling compression settlement has been basically completed, for the control of widening roadbed deformation settle-ment, to ensure the comfort of driving, based on the analysis and calculation and finite-element simulations and optimal design is made for steps size. Quality of subgrade is guaranteed based on the measures of improved compaction, cleaning, cutting slope, slope excavation step, setting the geotextile etc. |
