摘要

利用赣南地区的基础地质资料,分析了该区域在大受力背景下的应力调整方式。赣南新构造运动特征明显,NNE向、NW向及EW向构造体系受近东西向应力场作用在局部形成应力集中,并在多组构造交接复合处释放;新构造在对老构造的改造复合过程中,构造带上岩石常处于强烈破碎状态,积聚不了大的能量,因而不太可能发生较大(MS≥6 0级)地震。
Based on the geological structure in the south of Jiangxi, this paper has analyzed the stress adjustment mode in that area under the geological background press. The neotectonics features of that area are very evident. The stress concentrates under the action of the NNE-trending, NW-trending and EW-trending tectonic and releases at the conjunct part of several groups of tectonics. In the process of reforming and compounding the old tectonic by the new tectonics, the rock is always in strong fracture status and cannot accumulate enough energy to make a strong earthquake MS≥60 occur.
