贵州岩溶地区水库渗漏及地下水开发利用问题

贵州地质 1984年第1期 1-7页

作者：高平贵州科学院

岩溶地下水可分为三层:上层垂向渗灌,中层横向流动,下层是承压水比较静止,水库渗漏和地下水开发利用是中层。研究勘探中层,避免渗漏,必要时进行防渗工程措施是行之有效的。地下水的开发利用,应采取拦、蓄、引三位一体的方案为上策,是为... 详细信息

岩溶地下水可分为三层:上层垂向渗灌,中层横向流动,下层是承压水比较静止,水库渗漏和地下水开发利用是中层。研究勘探中层,避免渗漏,必要时进行防渗工程措施是行之有效的。地下水的开发利用,应采取拦、蓄、引三位一体的方案为上策,是为子孙万代的永久之计;“提”要因地制宜,要有节制的,要算水账,要统一规划部署。不要密集的打井,不要大量吸取地下水,不要长期的超过了它的补给来源,以致逐步降低了大面积的地下水位,后果是重要的。

贵卅南部泥盆系中下部发育着一套石英砂岩——蟒山石英砂岩(乐森(王寻),1929)。以往用传统地层学理论强行将其与时间地层单位统一,造成划分对比上的混乱。本文用多重地层划分的概念,对蟒山石英砂岩的穿时性作了讨论,并用古地质图等分析... 详细信息

贵卅南部泥盆系中下部发育着一套石英砂岩——蟒山石英砂岩(乐森(王寻),1929)。以往用传统地层学理论强行将其与时间地层单位统一,造成划分对比上的混乱。本文用多重地层划分的概念,对蟒山石英砂岩的穿时性作了讨论,并用古地质图等分析了穿时机制。重新确定了岩石地层单位—蟒山石英砂岩的定义。

It is well known that since the disintegration of the former Soviet Union, Russia has suffered detrimentally as a result of strategic pressure from the United States and Europe. After over ten years of concession and silence,Russia with Putin as the core counterattacks, deploying stunning tactics one after the other. These not only set up'loss limits',but also protected and won Russia's interests to the greatest extent, such that Russia not only won respect but also gained benefits. These stunning tactics are called'Russian Leverage'.

During solar eclipse, the lunar shadow moves through the earth's atmosphere with supersonic speed. Chimonas and Hines deemed that the shock waves produced by cooling of atmosphere would induce gravity waves, and both TIDs and atmospheric pressure changes can be detected in the ionosphere and on the ground respectively. Although the IGW signals from solar eclipse are usually quite weak, they can still be detected .The pressure changes on ground level occur near the region of eclipse, but can be detected even far beyond the path of eclipse. This article is the first one to report results of detecting pressure waves caused by solar eclipse in China.Druing the 23rd September 1987 annular solar eclipse, IGWs have been detected and recorded at infrasound observatories in Urumqi, Taiyuan, Xuzhou and Suzhou, which are situated within the path of annular eclipse, as well as in Beijing and Guiyang, which are situated on the opposite sides of this path. The signals are detected by microbarometers of condenser microphone type. After analysing the waveforms of the recorded signals numerically, the wave periods and wave amplitudes are determined to be within the ranges from 10 to 60 min and from 7 to 20 Pa (peak to peak ) respectively. The results from dynamical spectral analyses show that the spectral distribution of all the gravity wave periods from various observatories is continuous and possesses a common main period of 40 min. Moreover, there are waves with even longer periods in different observatories and their appearance times are quite different.
