通过对青藏高原气候变化预测情况的认识,采用数值模拟计算,对两种不同升温条件下多年冻土区的热状况及对年冻土退化范围进行了预测,并据此提出了气候变化背景下多年冻土区路基工程的总体设计原则。对升温条件下多年冻土区路基工程的稳定性进行了分析,总结了气候变化对青藏铁路多年冻土区路基工程的影响。
Based on the cognition of the climate change prediction in the Qinghai-Tibet Plateau, the thermal status of the permafrost region under two different heating conditions and the degradation range of the permafrost are predicted by numerical simulation. Based on this, the climate change background is proposed General Design Principles of Roadbed Engineering in Permafrost Regions. The stability of subgrade construction in permafrost region under the condition of increasing temperature is analyzed, and the influence of climate change on subgrade construction in permafrost region of Qinghai-Tibet Railway is summarized.
