This paper deals with the investigation of the data of variation of sea level continuously recorded during many years by 5 tidal stations located along the coast of the Gulf of Bohai. After processing the data and making various corrections, it was found that before the Haicheng Earthquake of 1975 the average sea level showed a ten'dency of steady rise within a broad area. For the recording stations closer to the epicenter of the earthquake, the variation of the sea level became more conspicuous...

This paper deals with the investigation of the data of variation of sea level continuously recorded during many years by 5 tidal stations located along the coast of the Gulf of Bohai. After processing the data and making various corrections, it was found that before the Haicheng Earthquake of 1975 the average sea level showed a ten'dency of steady rise within a broad area. For the recording stations closer to the epicenter of the earthquake, the variation of the sea level became more conspicuous and abrupt. However, before the Bohai Earthquake, occurred in the Gulf of Bohai in 1969, the mean sea level was lowered for a long period of time.

对多年来在我国渤海沿岸五个验潮站的海平面连续记录资料进行了各种改正和处理之后,发现1975年海城地震前平均海平面出现大范围稳定持续的上升趋势,震中区附近该平面的变化更为显著,并表现为突发性的变化.但1969年在同区发生的渤海大地震之前,则平均海平面经历了长趋势的下降.

This article describes a mathematical model for the tides in a bay. The objective is to anticipate with this model the effects that closing off of an estuary may have on the tides in an adjoining bay. As the area investigated is 105 km long and 25 to 65 km wide, a depth-integrated, two-dimensional model is employed. Schemes for finite-difference computations have been derived by applying the theory ofc haracteristics to the full equations of motion with the convective acceleration terms retained. Altogether...

This article describes a mathematical model for the tides in a bay. The objective is to anticipate with this model the effects that closing off of an estuary may have on the tides in an adjoining bay. As the area investigated is 105 km long and 25 to 65 km wide, a depth-integrated, two-dimensional model is employed. Schemes for finite-difference computations have been derived by applying the theory ofc haracteristics to the full equations of motion with the convective acceleration terms retained. Altogether 12 types each of land and water boundary conditions have been considered .In the first place, tides in the bay under natural conditions are modeled. By adjusting the resistance coefficient and by proper schematization of the topography of the bay, satisfactory reproduction of the tides can be achieved. Whereas the maximum deviation of the computed tidal stage from the observed is 0.26 m at high tide at a station where the tidal range is 6.20 m., the phases of computed and observed tides are practically identical at all tidal stations.There is a station where depth-integrated current data for a complete tide have been recorded. It is somewhat surprising that the current data are closely modeled in magnitude, phase and direction.On the basis of successful modeling of the natural tides, the closure of the estuary is next simulated and the corresponding tides in the bay computed. It is found that high water at the closure dam will come sooner than under natural conditions and that the high tide is lowered and the low tide elevated so that the tidal range at the closure dam is reduced somewhat.

The shanghai gravity tidal station is located at φ=31.1°N, λ=112°.2E, using a gravimeter type GS-15 No. 227 installed in a tunnel. The annual mean temperature in the tunnel is 18.8℃, the annual deviation of which is 0.3℃. The scale value of the gravimeter is 2.99 μgal/mm.

The annual mean temperature in the tunnel is 18.8℃, the annual deviation of which is 0.3℃. The scale value of the gravimeter is 2.99 μgal/mm. The data continuously observed from April to August in 1978 (142 days) were analysed by both the methods of Lecolazet and Venedikov. The results of analysis by the method of Lecolazet are as follows:δ(M2) = 1.142, δ(K1) = 1.164, δ(O1) = 1.192, δ(O1)-δ(K1) = 0.028, while that by the method of Venedikav are:0 δ(M2) =1.142, δ(K1) =1.166, δ(O1) =1.189, δ(O1)-δ(K1) =0.023.Besides, the accuracy of methods of Lecolazet and Venedikov were tested on the electronic computer DJS-18 of the Peking university. The test results are as follows:(1) For method of Lecolazet, the accuracy of determination of gravimetric factor δ of the main waves M2, S2, N2, K1, O1, is about 1%, while the accuracy of determination of the phase difference of the same main wave is about 1°.(2) For method of Venedikov, the accuracy of analysis depends on the length of the observational data, in general the longer the data, the more accurate the result. When the length of the data is 90 days, the accuracy of determination of the gravimetric factor δ of the main waves M2, S2, N2, K1, O1 is about 1% the accuracy of determination of phase difference of the same main wave is about 0.°5
