地下流体附加力源的研究新思路

A NEW TRAIN OF THOUGHT ON THE STUDY OF THE ADDITIONAL FORCE SOURCE OF SUBSURFACE FLUID

提出地下流体储量变化是地震和多种前兆发生的附加力源的新观点。认为多种天然的和人为的因素所引起的地下流体储量变化，是一种附加力源。它通过流体载荷、孔隙压力、动水压力及化学腐蚀等作用，促进地壳的构造变形，并导致多种地震前兆异常的产生；而流体载荷和构造变形，又可促进地震的孕育和发生。对于降水、地表水、开采等因素造成的异常变化，不能简单地当做干扰来加以排除，它本身包含有大量的地震前兆信息。论述了该思路的科学立论、观测事实与解释，研究的难点和解决途径等问题。

A new viewpoint that the variation of subsurface fluid reserves is an additional force source for the occurrences of earthquakes and many kinds of precursors has been put forward. The scientific argument of the train of thought, its observed facts and explanation, the research difficult point and the solving way have been discussed.
