深井水位降水效率随测层深度的变化规律模拟

SIMULATION OF VARIATION LAW FOR PRECIPITATION EFFICACY OF WATER LEVEL IN DEEP WELL WITH THE DEPTH OF SURVEYING LAYER

统计鲁北平原４井降水效率表明，地质类型相同的深井水位降水效率主要受控于测层埋深；规律性极强。笔者在统计基础上建立了模拟公式，并计算了不同深度测层的降水效率，与实际统计弥合度极好。笔者认为：对类型相同不同深度测层水位降水干扰排除过程中即可利用该式对其效率直接计算，免去了统计、修定的麻烦。

Statistics of the precipitation efficacies in the four wells located in the northern Shandong plain shows that the level precipitation efficacies in the deep wells having the same geological structure are controlled by the depth of surveying layers mainly, displaying a striking regularity. The author in this paper, on the basis of statistics, sets up a simulation formula,and calculates the precipitation efficacies of the surveying layers different in the depth, which is in keeping with pratically statistical results very well. The author believes the formula may be directly used to calculate the level precipitation efficacies of the surveying layers, the same on type but different in the depth, in the course of eliminating precipitation influence,so heavy work of statistics and correction can be ommitted.
