闽、台地区地震影响场的讨论

本文研究了闽、台地区地震烈度分布,计算了小震振幅及地震波能量的衰减,统计了小震与大震的烈度资料.说明地震烈度的分布是不均匀的,影响小震烈度分布的主要因素是地形与构造等,而影响大震烈度分布的主要因素则是构造与地震机制.小震振幅及地震波能量的衰减有方向性.文中计算的闽、台地区地震影响场,可为确定地震工程场地烈度提供资料.

STUDY ON THE THERMAL FIELD OF OBSERVATION CHAMBER AT CRUST DEFORMATION STATIONS

It is well known that the temperafure effect on the observation data of crustal deformation is the main interfering factor. with the development of measuring technique and data processing method, and the farther increasing requirement for the data quality, it is necessary and possible to research the temperature temperature field of the observation chamber. The results of temperature experiments from observation chambers at Sheshan station in Shanghai, Macheng station in Hubei and Mi yun station in Beijing are shown in this paper. Some suggestions for station relection, instruments installation and data analyses have also been proposed here.
