我国初期为监视地震活动,所建的跨断层短水准测量标志,多数埋设在第四纪黄土层中。事实证明松散的黄土层受周期性变化的气象因素干扰较大。为从根本上改善基础条件,我区安邱形变站,于1982年将跨沂沭断裂带的安邱——莒县大断裂的短水准标志,更换成钢管基岩标志。现就几个关键性的问题谈谈个人的意见,供同行参考。 In the early period of our country, for the monitoring of seismic activity, the short-span cross-fault leveling signs were mostly buried in the Quaternary loess layers. It turns out that loose loess layers interfered with meteorological factors that periodically changed. In order to fundamentally improve the basic conditions, the Anqiu deformation station in our district replaced the short standard mark of the Anqiu-Juxian Great Fault in the Yishu fault zone in 1982 with the mark of the basement of the steel pipe. Now on a few key issues to talk about personal advice for peer reference.
