“水力發电”1956年第8期刊登了孔令誉同志对“压水试驗前測定地下水安定水位”问题的解答,我感到有些问题。首先在透水性弱的地層加水測安定水位反而会加长测水位时間,这一点我不能同意。理论和經驗均証明,在大多数的情况下都是縮短了测安定水位时间的。加水确实可以改变地下水的化学成份,但若我們在加水之前取水样,就可以保証質量。我的意見:当鑽到含水層时应测安定水位,第一 “Hydroelectric Power” No. 8, 1956 Published Comrade Kong Lingyu’s answer to the “Determination of Groundwater Stabilization Level Before Pressurized Water Test”. I feel that there are some problems. First of all, in the weak permeability of water stratum water level will increase the water level measurement time will be longer, I can not agree at this point. Both theory and experience show that, in most cases, the duration of the test and determination of water level is shortened. Adding water can indeed change the chemical composition of groundwater, but if we take a water sample before adding water, we can guarantee quality. My opinion: When drilling into the aquifer should be measured to determine the water level, the first
