Based on statistical analysis of disced rock cores and rockburst about rock mass in exploration adit at the dam site where high ground stressis surrounded the causes of high ground stress are discussed in many respects, combined with characteristics of ground stress field, including the power source condition which is the regional tectonic setting and geological conditions, power storage conditions which is characteristic of lithology and structure of rock mass, power transformation and adjustment which is late reformation of rock mass. It is considered that high ground stress release is synthetical result caused by factors mentioned above.

针对坝区特定的高应力条件下岩体的应力释放现象，包括岩芯饼裂和勘探平硐岩爆发育普遍的特征，在统计分析的基础上，从力源条件-区域构造背景和地质构造条件、能力存储条件-岩性特征和岩体结构条件、后期演化-能量释放、转换与调整等分析的基础上，结合坝区地应力场分布的特征阐述了坝址区高地应力成因，认为坝区高地应力释放现象是上述各因素综合作用的结果。
