摘要
文章以江苏省大丰台、盐城台、淮阴台、海安台、射阳台井下摆观测为例，比较它们的观测结果。分析认为井下摆的观测效果不仅与地面复盖层的厚度有关，而且与井下摆周围的环境干扰、观测用井的质量有关。为了提高井下摆观测效果，应尽量减少环境干扰，并注意井的垂直度和固井，文章还指出，沿海地区井下摆受海浪干扰相当显著的。
As an example of the observation of the borehole pendulums in seismic stations ofthe Dafeng,Yancheng, Huaiyin,Haian and Sheyang,the article has compared their ob-servation resuIts. The analysis indicates that the efficiency of the borehole pendulumsobservation is not only related to the depth of the surface layer,but also related to thedisturbance of the environment surrounding the well and the quality of the observationwell.In order to raise the efficiency,We should reduce the environment disturbance andpay attention to the vertical degree and the fixing of the wells. The article also points outthat the disturbance of the sea wave is very significant.
