穩進地表火
英文
creeping fire-
The reason for the moderate and large earthquake of zhengjiang block could be attribute as such features : because of the structure ' s more rigidity and the rising of the several interfaces in the crust, the energy from the deep crust of upper mantle is transported to the middle or upper crust persistently. thus it always accumulates at some locations and this may lead to eart
由於地表火山活動的停止，來自中下地殼和上地慢的大部分能量得不到釋放，從而在有利的構造部位積聚，進而在流體的作用下，或在其它外動力誘發下，導致孕震系統失穩而發生地震。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。
