郑州铝厂位于黄河南岸超河漫滩Ⅱ—Ⅲ级阶地上。厂区分布为第四纪黄土状亚粘土。廿多年来,经过多次农田灌溉,使黄土状亚粘土的工程地质性质发生了不同程度的变化。本文根据多年的资料对郑州铝厂一带的黄土状亚粘土,因农田灌溉引起的工程地质性质的变化进行初步的探讨。 解放初期,郑州铝厂地区很少灌溉。随着农田水利事业的发展,该区的灌溉面积逐渐扩大。灌溉水源
Zhengzhou aluminum plant is located in the south bank of the Yellow River floodplain Ⅱ-Ⅲ terrace. The plant area is distributed as Quaternary loess-like loam. Over the past 20 years, after several times of farmland irrigation, the engineering geology of loess-like loam has changed in varying degrees. Based on many years’ data, this paper discusses the loess-like loam in Zhengzhou Aluminum Plant and the change of engineering geological properties caused by farmland irrigation. In the early days of liberation, Zhengzhou Aluminum Plant was rarely irrigated. With the development of farmland water conservancy, the area of irrigation has gradually expanded. Irrigation water
