The results demonstrate that the upper limit of permafrost in this area had declined from 1970s to the middle phase of 1990, and permafrost has appeared degenerate tendecy, but since middle 1990s, permafrost have a stable state ; ground temperature of roadbed near the earth surface is higher than that of the natural ground, thawing time of roadbed near the earth surface is longer than that of the natural ground, the heat income within the permafrost is greater than the heat release from the permafrost during anannual period, the heat accumulation within the permafrost is temporarily appeared as temperature rising, but with the heat accumulation within permafrost growing up year by year, permafrost temperature will become higher gradually, and strong thawing of permafrost could be happened in the region
結果表明：風火山地區從20世紀70年代到90年代中期凍土上限下降，凍土出現退化現象，從90年代至今凍土趨于穩定；路基近地表地溫明顯高於對應天然地表下的地溫，路基近地表經歷的融化期長于對應天然地表，進入多年凍土區的熱收支也呈現出吸熱明顯大於放熱的周期性變化，進入多年凍土的熱積累暫時以增高地溫耗熱為主，但隨著凍土吸熱量的逐年積累、凍土溫度的不斷升高，本區凍土可能發生強烈融化。According to feature that goal function has more than one local extremum in displacement back analysis for underground engineering, a new means of displacement back analysis for underground engineering has been established through adopting fem and self - adaptation idea on the basis of the improvement of the determining method of control parameters, such as initial temperature and number of state choice and annealing strategy, moreover, the relevant analytic software is developed
摘要本文針對地下工程圍巖位移反分析問題的目標函數存在多個局部極值的特點，在對模擬退火演算法進程中控制參數，即初始溫度、每一溫度下的狀態選取次數和退火策略的確定方法加以改進的基礎上，引進有限元分析手段和自適應的思想，建立了基於改進模擬退火演算法的位移反分析方法，並開發了相應的分析程序。
