摘要
利用赤平极射投影等资料，计算了丹江水库及邻区的主应力方向，结果表明：主压应力为北东东向，主张应力为北北西向，现代构造应力场与新生代以来应力场基本一致；晚第三纪以来，该区地壳应力场相对稳定。
In this paper,based on the data of the stereogram and others,the orientation of maximum principal stress in the region of Danjiangkou reservoir is calculated. The results show that the orientation of compressive principal stress is NFE and the orientation of tensile principal stress is NW.The modern tectonic stress field is in keeping with neotectonic stress field. Thus it is considered that the crustal stress field in the area investigated has always been relatively stable since Neogene.
