| 9. | It brings ollt a fem model to calculate lateral earth pressures behide the integral - abutment with considering the inieraction of eallh and abdrient . aiming at the two inherent behavioral deficiencies inherent in all iabs " summer lateral earth . pressure increases after each temperature cycle ; and the settlement adjacent to each abutment develops after each temperatllre cyc1e , this article brings out two method to solve or relieve the above two problems
本文针对整体式桥台桥梁的台后填土存在着土压力逐年增大以及台后填土的沉降问题，建立了整体式桥台桥梁的台与土共同作用的有限元计算模型；并以台后填土为研究对象，提出两种主要处理方法：台后设置eps压缩层方案，选用台后土加筋或置换轻填土方案；通过有限元分析计算了季节性温度荷载变化下产生的位移在上述处理方法中对于台后土压力的影响。 |
