Zusammenfassung:The invention provides an experimental method for simulating strong-disturbance triggered rock burst of a dike. The method comprises the following steps: loading X-direction stress and Z-direction stress on to a first test piece of rock, maintaining two horizontal surfaces in a Y direction to be free surfaces, wherein the X-direction stress is static loading stress, continuously increasing the Z-direction stress until the first test piece is damaged and recording basic parameters during damage; loading X-direction stress and Z-direction stress on to a second test piece of rock, maintaining the Y direction to be in a free state, wherein the X-direction stress is static loading stress and the Z-direction stress is initial static loading stress; and loading X-direction or Z-direction impact disturbance load onto the second test piece of rock to subject two horizontal free surfaces of the second test piece of rock in the Y direction to ejection damage, and observing and recording the ejection damage process of br
