ONE WAY TO EXPOSE PALEOSEISMOLOGY TRENCH
-
摘要: 在活动构造研究中,开挖探槽,发现隐藏于地下的古地震活动迹象是一项重要的突破。通过详细论述探槽方法研究古地震的原理及选点布槽、设计开挖、探槽记录、采集年龄样品等环节,较系统地总结了探槽研究古地震的整个工作流程。Abstract: Paleoseismology research is an important part of active tectonic research;meanwhile, the research has been an important role in the evaluation of the seismic risk.Modern paleoseismology research was formed at the last of 70s of 20th century.With several decades' development and accumulation, a quite completed set of research technology and method for paleoseismology has been formed.As a technology to expose the paleoearthquake's active evidence hidden under the ground, excavate trench is an important breakthrough.
