Abstract In deep engineering，the development and application of novel metallic materials has attracted many attentions. Although previous studies have demonstrated the importance and mechanical advantages of using high-strength and high-toughness steels in rock support system，its energy absorption characteristics under the influences of prestressing and rock loading remains still unclear. Therefore，based on the crystal plasticity method，this study takes novel high-strength and high-toughness bolt steel as an example to compare and analyze the mechanical and energy absorption characteristics of various metallic rock support materials. Meanwhile，the crystal plasticity model based on underlying physical mechanisms was used to study the effects of varying prestresses and rock loading rates on the energy absorption characteristics of high-strength and high-toughness bolt steel. The research results show that the development of energy absorption density of conventional metallic rock support materials meets a bottleneck. Distinct from the trade-off relationship between energy absorption density and ultimate tensile strength of conventional metallic rock support materials，the high strength(＞940 MPa) and large elongation(＞0.4) characteristics of novel high-strength and high-toughness bolt steel result in its extremely high energy absorption density of 3.5?108 J/m3，which is about 3–7 times that of conventional metallic rock support materials. The results of crystal plasticity simulations show that the material’s energy absorption characteristics can be further improved by adjusting the prestress and controlling the rock loading rate. For instance，the effective energy absorption rate of the material can be rapidly increased by applying high prestress，and it can resist the influence of rock loading rate. As the prestress is increased close to the yield stress of the material and the rock loading rate is controlled below 10－2 MPa/s，the high-strength and high-toughness bolt steel can obtain the largest effective strain(＞0.54) and the highest effective energy absorption density(＞4.5?108 J/m3)，which can optimize the energy absorption characteristics of high-strength and high-toughness bolt steel. The research results provide theoretical basis and technical guidance for practical application of high-strength and high-toughness steel for rock support engineering in high in-situ stress field.

Key words： rock mechanics energy absorption high-strength and high-toughness bolt steel surrounding rock large deformation prestress loading rate crystal plasticity
