通过室内模型试验,用农用式手动喷雾器喷水来模拟降雨,同时用保暖灯来模拟日照。在模型箱内不同位置布置温度和水分传感器,以寻求降雨和日照对不同位置黄土温度的影响,进而找到气候变化对黄土边坡的影响范围及影响规律。试验结果表明,边坡内部土体各点的温度对外界条件变化的响应表现为滞后性。
Through the indoor model test, using agricultural hand-held sprayer to simulate rainfall, while using warm light to simulate the sunshine. Temperature and moisture sensors are arranged at different positions in the model box in order to seek the influence of rainfall and sunshine on the loess temperature in different locations so as to find the influence range and influence law of climate change on the loess slope. The experimental results show that the response of the temperature at each point of the soil inside the slope to the change of the external conditions is lagged.
