一种用于花岗岩单轴和三轴压缩试验的应力应变数据库

提出自主构建的一种关于花岗岩“应力应变”曲线研究的数据库。涵盖多种地区（江西省赣南某金属矿山、河南省辉县、甘肃东部陇山西麓、河南洛阳、、山东平邑、美国佛蒙特州 Burlington 地区西南部、新加坡 Bukit Timah、 新加坡 Bukit Timah、四川盆地及周边复杂地层、四川阿坝某水电站地下厂房（高应力硬岩环境）、中国甘肃北山地区、北山地下实验室场址新场场区、湖南岳阳、湖北黄冈、湖南汨罗地区、湖南岳阳、湖北黄冈，等多个地区）的9454余个应力应变数据，包括（弹性模量、最大荷载、峰值应力（单轴抗压/压缩强度）、花岗岩埋深、试验系统、最大主应力、峰值应变、破坏模式、岩样尺寸，等条件下的实验参数筛选功能快速进行区分对比。通过对多源数据的标准化整合，形成集区域性、多工况于一体的基础数据平台，可有效支撑上述地区范围内花岗岩力学行为的系统性研究，为工程实践中花岗岩资源的高效利用提供科学数据支撑。

We propose a self-developed database for research on granite stress-strain curves. It contains more than 9454 sets of stress-strain data collected from multiple regions including: a metal mine in Gannan area of southern Jiangxi Province, Huixian of Henan Province, the western foothills of Longshan Mountain in eastern Gansu Province, Luoyang of Henan Province, Pingyi of Shandong Province, southwestern Burlington area, Vermont, USA, Bukit Timah, Singapore, Bukit Timah, Singapore, Sichuan Basin and its surrounding complex strata, underground powerhouse of a hydropower station in Aba, Sichuan Province (high-stress hard rock environment), Beishan area of Gansu Province, China, Xinchang Site of the Beishan Underground Laboratory, Yueyang of Hunan Province, Huanggang of Hubei Province, Miluo area of Hunan Province, Yueyang of Hunan Province, Huanggang of Hubei Province, etc. The database covers experimental parameters such as elastic modulus, maximum load, peak stress (uniaxial compressive strength), buried depth of granite, test system, maximum principal stress, peak strain, failure mode, specimen size, and is equipped with experimental parameter screening functions to quickly conduct comparative analysis across different conditions. Through standardized integration of multi-source data, a basic data platform integrating regional characteristics and multiple working conditions has been established, which can effectively support systematic research on the mechanical behavior of granite in the above-mentioned regions, and provide scientific data support for the efficient utilization of granite resources in engineering practices.
