| 摘 要： | 随气候条件而变化的边界条件的确定是岩土工程中非饱和土数值分析的一个难题。介绍了农业学中的土与大气相互作用分析中的一些应用较为广泛的方法，并采用空气动力学法和微气候能量平衡法相结合的方法确定土-气界面的边界状态，分析了法国鲁昂试验路堤的路堤填土与大气在2005年1月的能量交换，以及在此期间填土内的温度、含水率和吸力的变化，并与实测结果进行了对比。结果表明，农业学中所采用的能量平衡以及能量计算方法可以有效地应用于岩土工程非饱和土的数值分析中，解决随气候而变化的边界条件的确定问题。

| Abstract: | The determination of boundary condition which changing with weather condition is always a challenge problem in geotechnical numerical analysis of unsaturated soil. Some methods used widely in agriculture for soil-atmosphere interaction analysis are introduced. Moreover, the energy balance method and aerodynamics method are used to setting the boundary condition in the analysis of Rouen test embankment in France. Embankment behavior in January 2005 is simulated; and results including energy exchange between the embankment soil and atmosphere, soil temperature, soil volumetric water content and suction are given. It is shown energy analysis methods used widely in agriculture are also effective in geotechnical problem analysis. |
