The geochemical behaviour of heavy metals in river and its effect on shallow aquiferous system of both sides of the river are studied by theoretic calculation and experiments. It is shown that the effect on shallow aquiferous system of both sides of the river is through the medium of artificial factor rather than with hydraulic alternation and diffusion process in a network of waterways of plain area where the permeability of aquifer is weak.

As pointed out by Prof. P. Melchior and Prof. Cai Zuhuang, the phase differences between well tide and fide-generating potentials are 180°. On basis of earth tide theory, phase shift in observation of tidal fluctuation in a deep well is discussed here and the observation results of the well No. 14 in Beijing are given: O_1,178°; Mz, 150°. Also main effects on phase shift in observation of well tide are discussed according to inelastic response of a well-aquifer system to tide-generating potentials and knowledge...

As pointed out by Prof. P. Melchior and Prof. Cai Zuhuang, the phase differences between well tide and fide-generating potentials are 180°. On basis of earth tide theory, phase shift in observation of tidal fluctuation in a deep well is discussed here and the observation results of the well No. 14 in Beijing are given: O_1,178°; Mz, 150°. Also main effects on phase shift in observation of well tide are discussed according to inelastic response of a well-aquifer system to tide-generating potentials and knowledge of hydrogeology. It is concluded that a phase shift in observation of well tide result from inelastic response of a well-aquifer system to tide-generating potentials and that the phase shift depends on tidal frequency,radius of well, thickness of aquifer, permeability of aquifer and specific storage of aquifer.Moreover, influence of radius of well, thickness of aquifer and permeability on phase shift in observation of well tide is simulated numerically.

P.Melchior教授和蔡祖煌等先后指出,深井水位固体潮与引潮力位之间的相位差为180°。本文根据固体潮理论论述了深井水位固体潮的相位差,给出了京14井井水固体潮的相位差;O_1波,178°;M_2波,150°。文中还从井孔含水层系统对引潮位的非弹性响应出发,结合水文地质学,讨论了影响深井水位固体潮相位差的主要因索。结果表明,深井水位固体潮的相位差是由井孔含水层系统对引潮位的非弹性响应所致;它依赖于潮波频率、井孔半径、含水层厚度以及含水岩层的渗透率和储水率。最后,通过数值计算,模拟了井孔半径、含水层厚度和渗透率对井水固体潮相位差的影响。

Marine invasion is a kind of geologic hazard co made by nature and mankind Since 70's, marine invasion in Liaoning Province have gotten more heavily with the invasion area wider and the speed of invasion higher At prsent,marine invasion in Liaoning province has cause heavily hazard to the production of industry and agriculature, and to the people's living Marine invasion in Liaoning Province is mainly caused by lithological characteristics, texture, thickness, permeability of aquifers, the closely hydraulic relationship between undergraoud water and sea water, Neotectonic movements and paleoclimatic changes since Quaternary, and manmade overexploitation Based on the studies on the distribution and hazard degrees of marine invasion in Liaoning Province, it is proposed to take some controlling measure, such as, to controll the exploiration of undergraound water near the sea, to inject fresh water into aquifers, to dig intercepting wells and then to withdrawal the sea water, to construct a groundwater reservoir, etc

海水入侵是在自然和人为因素综合作用下形成的地质灾害。辽宁省海水入侵自 70年代以来呈逐渐增加趋势 ,具有入侵面积广、发展速度快等特点。目前海水入侵已成为我国较为突出的地质灾害 ,给工农业生产和人民生活造成很大危害。针对海水入侵形成机制及危害程度的地域性 ,目前已采取不同的防治措施 ,如控制开采 ,人工回灌 ,修建地下水库等 ,取得一定效果。
