冻土的物理、力学和热学性质均与温度密切相关。就热学而言,热收支是衡量自然冻土和冻土区各种工程稳定性的重要指标。目前,热收支计算还主要是通过导热系数来计算通过活动层的热流。盛煜(2002,2003)计算并比较了天然地面和路基中心孔路面下通过0.5~1.0 m土层的热流[1-2]。盛煜(2003)利用保温板上下面温度曲线对时间求积分,再乘以导热系数就得到了通过保温板的热流[3]。孙志忠(2004)比较了块碎石层下0.2~0.7 m范围内的热流通量,证明块石的降温效果更好些[4]。牛富俊(2003)计算了通风管路基2.5~3.0 m含土冰层的热流量[5]。俞祁浩(2004)推导出在试验条件下热量比等于温差比,来比较自控与无自控通风管路基的效果[6]。俞祁浩(2009)选取温度场稳定且基本没有发生相变的3.0~3.5 m含土冰层进行计算,来比较拥有自控系统和没有自控系统的通风路基的热流量(收支)和热流密度[7]。吴青柏(2005,2008)分析了块石路基下0.5~1.0 m土层的热收支[8-9]。于晖(2009)通过比较路基下原天然上限处和天然孔上限处热流和热收支的变化,来解释路基下冻土上限抬升的现象[10]。

The physical, mechanical and thermal properties of the permafrost are closely linked with temperature. In terms of thermal property, heat budget is an important indicator to measure the stability of natural permafrost and that of projects in permafrost regions. At present, the heat budget is mainly gained by calculating the heat flow through the active layer with the thermal conductivity. The heat flux between 0.5 and 1.0 m depths under the natural ground and that under the embankment (center hole) were calculated and compared (Sheng et al., 2002, 2003a). The heat flux through insulation board was gained with time quadrature of the temperature curves above and below the insulation board and the thermal conductivity of the board (Sheng et al., 2003b). The heat flux between 0.2 and 0.7 m depths under block-rock layer and that under crushed stone layer was compared, and proved that the cooling effect under block-rock layer is better (Sun et al., 2004). The heat flow between 2.5 and 3.0 m depths under duck-ventilated embankment was calculated (Niu et al., 2003). It was deduced that the ratio of difference in temperature equals to the heat radio in its experimental conditions, and the effect of auto-temperature-controlled ventilation embankment and ordinary ventilation embankment was compared (Yu et al., 2004). The layer between 3.0 and 3.5 m depths was selected to calculated heat budget, of which was constituted with thermal stable soil-poor ice, and the heat budget and heat flux of auto-temperature-controlled ventilation embankment and ordinary ventilation embankment was compared (Yu et al., 2009). The heat budget between 0.5 and 1.0 m depths under block-rock layer embankment was analyzed (Wu et al., 2005, 2008). With comparing the heat flux and heat budget between the natural permafrost and that of the embankment, the uplift of the permafrost table was explained after embankment construction (Yu et al., 2009).

Frost earth's physical, mechanics and thermal properties are closely linked with temperature. In terms of thermal property, heat budget is an important indication of engineering stability of natural frost earth and frost earth region. At present, heat budget is used to measure heat flux at mobile layer mainly through coefficient of heat conductivity. Sheng Yu measured and compared different heat flux that goes through soil lay with 0.5~1.0 m thick under natural ground and roadbed.

The physical,dynamic and thermal properties of tundra are all closely connected to its temperature. In thermotics, the heat budget is crucial to measure all kinds of project stablities of natural tundra and permafrost regions. But currently, it is mainly calculated by the heat flux passing through the active layers with the thermal coefficient. Yu Sheng(2002,2003), has calculated and compared the heat flux[1-2] of 0.5m-1.0m soil layers below the ground floor and the subgrade surfaceformation. he(2003) also calculated the integral of time with the temperature curve of both sides of the insulation board, this way the heat flow through the board comes out easily if we multiply the result by the thermal coefficient.
Zhizhong Sun(2004) did the comparision of the heat flux in an area of 0.2m-0.7m below between the stone and rubble layers and came to the conslusion that rubbles did a better job in desuperheating.[4] Fujun Niu(2003) also calculated the flux of the ice-soil layer from 2.5m to 3.0m of the vent-pipe bed . The effects of automatic vent-pipe and the normal one can also be compared due to the deduction by Qihao Yu that the ratio of difference in temperature equals to the heat radio in experimental conditions. Qihao Yu did his calculations by choosing the stable-temperaturefielded ice-soil of 3.0m-3.5m whose temperatre is rarely changed , then compared the heat flux(budget) and heat density of the automatic and the non-automatic vent pipe beds. Qingbo Wu(2005,2008) analysized the heat budget of 0.5m-1.0m soil layer below the stone-bed.[8-9] Hui Yu(2009) has explained why the upper limit of the tundra below the subgrade has uplifted by comparing the changes of the heat flux and heat budget from the natural orifice upper limit and the original one.[10]
