摘要
以室内一维土柱试验和室外水平衡小区观测资料为基础 ,对农田排水条件下降雨入渗补给与地下水埋深关系进行了分析 ,根据降雨、蒸发与地下水埋深关系相似的规律 ,仿照国内外排水计算中较为广泛应用的阿维里扬诺夫经验公式的结构形式 ,建立起降雨入渗补给与地下水埋深的关系 ,并采用室内外试验资料对该关系式进行了验证。
Based on experimental data from laboratory and field experiments, the relationship between rainfall recharge and groundwater level under farmland drainage is analyzed in this paper. According to similar raw that the relationship among rainfall, evaporation and groundwater level is similar in all regions, an equation described relationship between rainfall recharge and groundwater level are established and calibrated with experimental data. The research results are important theory basis for drainage system design.
