分析铁门关钻孔应变记录地震的空间分布、震级和震深特征，选取32组较明显的固体潮畸变现象进行研究，结果表明：钻孔应变固体潮畸变主要表现为外部环境干扰、强远震前畸变和同震响应3种类型。

This paper preliminary analysis the characteristic of seismic spatial distribution， magnitude and depth of Tiemenguan borehole strain，studies 32 groups of obvious solid tide distortion phenomenon，the results indicates：the borehole strain solid tide distortion mainly Performance for external environment，strong far pre-earthquake distortion and coseismic response three types.
