Zusammenfassung:	The present invention discloses a method for monitoring stress gradient of a concrete dam. The method comprises: 1. calculating the dam body principal stress distribution condition of a key part through monitoring data of a multi-directional strain gauge set arranged at the key part of the concrete dam; 2. arranging a plurality of stress monitoring sensors in the drilling hole in a serial connection manner; 3. calculating the spatial position coordinate value of each stress monitoring sensor from an opening of the drilled hole to the hole bottom; and 4. monitoring in real time according to the dam working condition, selecting actually-measured data for comparison and calculation, and acquiring a principal stress gradient path and a corresponding principal stress gradient value.
