摘要:
通过季节冻土区现场测试浅层黄土温度和含水量的变化,研究了冬季温度对浅层黄土水分场影响的变化规律.测试得出:随着地表温度的降低,冻结锋面向下移动,冻土层含水量越来越大,冻土层下方未冻土含水量明显降低.建立了模拟现场的水热耦合数值计算模型,并计算了彬县的水分场变化,计算结果和实测基本吻合,验证了该计算模型及参数选取的合理性,该计算模型可用于模拟黄土高原地区冬季浅层黄土水分迁移.
Abstract:
Through field test temperature and water content of shallow loess in seasonal frozen ground, the changing rules of the influence of winter temperatures on water field in shallow loess is studied. Testing results show that with the decrease of surface temperature, the freezing front move downward. Then the water content of frozen soil zone increases and reduces significantly below the frozen soil zone. The water-thermal coupling numerical model for simulating field is established and the water field changing of Binxian County calculated. The numerical result is in agreement with the test data. It shows that the calculation model and parameter selection is reasonable. The model can be used to simulate water migration of shallow loess in Loess Plateau in winter
