| 摘 要： | 在路堤施工中,为了控制施工进度,指导后期的施工组织和安排,同时保证路堤的稳定与使用,需对路堤不同时刻的沉降及最终沉降量进行预测和计算。对于天然地基,其沉降预测和计算方法较多,且有各自的适用性。阐述了天然地基沉降预测和计算方法,以及各种方法的优缺点,可为类似路基工程设计提供参考。

| Abstract: | The design idea of Qinghai-Tibet Railway permafrost subgrade is active cooling,which has been widely recognized.This paper compared the measured subsurface temperature data of different permafrost subgrade in Qumar River region.The result shows that permafrost under ordinary subgrade obviously trends to be melt,which need to take protecting measures in time.Thinner stone subgrade has a certain role in protecting permafrost,but the effect is not obvious.Therefore,it is recommended to add block stone to form ... |
