青藏高原重大工程区地应力分布规律

地应力是指存在于地壳中的应力，即由于岩石形变而引起的介质内部单位面积上的作用力。本专题通过青藏高原重大工程区的文献搜集与钻孔测试得到重大工程区地应力数据。原始数据资料精度可靠，并有专人负责质量审查；经多人复查审核，其数据完整性、位置精度、属性精度均符合有关技术规定和标准的要求，质量优良可靠。该数据能够为研究青藏高原重大工程扰动灾害、重大自然灾害的发育规律以及其他与地应力相关研究工作提供基础数据支撑。

In-situ stress refers to the stress existing in the Earth's crust, i.e., the force per unit area within the medium caused by rock deformation. This dataset collects in-situ stress data for major engineering zones on the Qinghai-Tibet Plateau through literature collection and borehole testing. The original raw data has reliable accuracy, with dedicated personnel responsible for quality inspection. After multiple rounds of review and verification, the data's integrity, positional accuracy and attribute accuracy all meet the requirements of relevant technical regulations and standards, ensuring excellent and reliable data quality. This dataset can provide basic data support for studies on the disturbance disasters of major engineering projects on the Qinghai-Tibet Plateau, the development laws of major natural disasters, and other research related to in-situ stress.
