摘要
本文以弹性薄板有限元理论为基础,对弹性半空间地基及文克勒地基上路面板的荷载响应进行了较系统的对比分析,得出了不同板厚、不同荷位下两种地基模量换算关系的诺谟图;最后对两种地基模型进行了综合评述,结论认为,K 地基模型较好地反映了板下地基的实际工作状态。
Based on the elastic thin plate finite element theory,by ana- lyzing the loaded response of rigid pavement slab on the elastic Semi-infinite foundation and Winkler foundation,the nomographs for subgrade reaction K comparable to Young's modulus E was developed,After a review of two foun- dation models,it was concluded that Winkler foundation model can better re- veal the working condition of the subgrade under the rigid pavement.
