据一些群测经验介绍,土应力仪在大震前有所反应,从而被誉为一种较好的前兆手段,并得到了推广。岳阳地区有十四个测点安装了土应力仪,包括75—1、DWL—1和ZD—1,但不管哪一种,在无震情况下,都有“趋势性”变化,也有“突发性”变化,原因何在?这样的土应力资料怎样处理?本文就浅谈这方面的点滴认识。 According to some group survey experience, geotechnical stress response before the earthquake, which was hailed as a better precursor means, and has been promoted. There are 14 measuring points in Yueyang area where geotechnical instrumentation is installed, including 75-1, DWL-1 and ZD-1. However, no matter what type of geostress exists, there are “trend” changes in the absence of any earthquake. Fat "changes, what is the reason? How to deal with such a soil stress information? This article on this bit of understanding.
