一般认为,抽水试验只能安排在非抽水季节、水位稳定、外来干扰因素较少的情况下,求取的参数精度较高。而在我国广大的北方地区,非开采期正值天寒地冻的冬春季节,开展试验工作有许多不便之处,如抽水设备的安装、抽水出路和冬暖设备等,因此,开采灌溉季节能否进行抽水试验求取参数,直接影响着勘探速度和地下水资源评价工作。 为此目的,我们于1979年8月地下水位下降最大
It is generally believed that the pumping test can only be arranged in the non-pumping season, the water level is stable, external interference factors less, the higher the accuracy of the parameters. However, in the northern part of our country, the non-mining period coincides with the winter and spring when the weather is freezing. There are many inconveniences in carrying out the pilot work, such as the installation of pumping equipment, the pumping out of water outlets, and the warm-winter equipment. Therefore, the irrigation season Whether pumping tests can determine the parameters directly affect the exploration speed and groundwater resources assessment. For this purpose, we saw the largest drop in groundwater level in August 1979
