| Abstract: | Using the data from long-term observation system of permafrost area along Qinghai-Tibet Railway,the stability of the subgrade engineering of Qinghai-Tibet Railway is analyzed.The stability of most subgrade engineering is in a good condition,but the subgrade sinkage is formed only in several areas.After taken measures including drainage and thermal protection,the data prove that the disease subgrade tends to stabilize.Reasonable measures can protect subgrade engineering. |
