文中介绍甘肃省东部地区1985年以来在重力、倾斜、水平应变和水位等固体潮方面的测量概况,给出了各台(项)全系列观测资料作整体调和分析计算的潮汐参数,分析了液态地核共振效应对重力、水平线应变和水位固体潮周日波潮汐因子的影响以及地壳构造横向不均匀性对倾斜固体潮潮汐因子的影响。结果表明,兰州重力仪、石英水平伸缩仪和甘06井等水位井的结果清楚地显示出液核共振效应对K_1波振幅的缩小作用和对ψ_1波振幅的放大作用,且重力和伸缩仪NS向结果所揭示的地球模型更接近莫洛金斯基的地球型Ⅱ;倾斜固体潮潮汐因子的实测结果明显地受地壳构造横向不均匀性影响,其中水管倾斜仪受影响的程度又明显地大于水平摆倾斜仪,兰州和宕昌两地南北向的非均匀性明显大于东西向,而宕昌地区的非均匀性又明显大于兰州地区。
This paper introduces the survey of the tide of gravity in the eastern Gansu province since 1985, such as gravity, tilt, horizontal strain and water level. The tide parameters of the whole series of observations of each station are analyzed and calculated. Effects of the Earth’s Nuclear Resonance on the Gravity, Horizontal Strain and the Daily Wave Tide Factor at the Water Level and the Effect of Lateral Unevenness of Crustal Structure on the Tidal Factor of Tilting Solid Tide. The results show that the results of Lanzhou gravimeter, quartz extensometer and Gan 06 well clearly show that the liquid crystal resonance effect reduces the amplitude of K_1 wave and amplifies the amplitude of ψ_1 wave, and the gravity and extensometer NS The results show that the Earth model is closer to the Molokinski Earth II; the measured results of tidal solid tide factors are obviously affected by the lateral inhomogeneity of the crustal structure, and the degree of impact of the water pipe tilt meter is significantly greater than Horizontal tilt inclinometer, Lanzhou and Dangchang north-south non-uniformity is significantly greater than the east-west, while the non-uniformity Dangchang area was significantly greater than the Lanzhou area.
