摘要
通过建立沥青混凝土加铺层结构有限元模型,分析了飞机偏荷载作用下加铺层厚度和增设土工合成材料对加铺层结构响应的影响,明确了这两种措施对延缓荷载型反射裂缝的作用。
Based on the established asphalt concrete overlay structure finite element model,the article analyzes the influence of the overlay thickness and the added soil engineering compound material on the structural response of overlay under the partial load of airplane,and makes clear the functions of these two measures for delaying the loading reflection cracks.
