Advance of in-situ stress measurement in China

Journal of Rock Mechanics and Geotechnical Engineering, 2011
In-situ stress is an essential parameter for design and construction of most engineering projects that involve excavation in rocks. Progress in in-situ stress measurement from the 1950s in China is briefly introduced. Stress relief by overcoring technique and hydraulic fracturing technique are the two main techniques for in-situ stress measurement in ...
