This paper conducts the laboratory test on rock samples from Xirangpo banks of Badong Town. The rock energy dissipation characteristics of the Middle Triassi Badong Formation are analyzed. Furthermore, the paper analyzes the laws of rock energy and discusses the strength characteristics and the failure regularity of bank slope. The paper indicates the follows: 1) by compression test, failure .mode of rock can be divided into four categories; 2) the hardness of rock can be characterized by energy of external load input before peak, rock failure and damage energy and unit length of the crack energy consumption rate, rock usually performance brittle failure; and 3) at the areas of mineral composition changes in rocks, the indicators of rock energy analysis have shown apparent fluctuation.
