The Geostress Measurement Laboratory

The lab of geostress measurement, the first institution on geostress monitoring and research was first established by Professor Li Siguang in late 1950s, mostly for earthquake monitoring and prediction. Subsequently, theories and methods of geostress measurement have been developed and greatly improved; a variety of equipment and devices on geostress measurement have been developed through years. At present, methods on geostress measurement include piezomagnetism, hollow inclusion, hydraulic fracturing, borehole breakout, acoustic emission, and anelasticity recovery.  Continuous geostress monitoring include a variety of comprehensive methods, such as piezomagnetic stress monitoring method, capacitive borehole strainmeter method and volumetric borehole strainmeter method, which are widely used in major projects on geodynamic research, geological disaster prediction, water conservancy and hydropower enginnering, site-choosing for rail and road tunnels,  the nuclear waste disposal and strategic oil reserves.
