| 摘 要： | 通过岩体声波测试,确定了岩体的损伤范围,并确定了损伤区岩体的损伤因子。根据损伤因子的确定结果,利用Hoek-Brown强度准则将岩块力学参数进行折减,确定出岩体力学参数。将确定的岩体力学参数用于边坡稳定性分析,分析结果与现场实际是一致,说明岩体损伤测试结果符合工程实际的。

| Abstract: | Through the sonic test, determine the extent of rock damage and the damage factor among the damage zone. According to the results of damage factors, rock mechanics parameters are confirmed by making use of Hoek-Brown strength criterion to reduce parameters of rock mechanics. Apply rock mechanics parameters to slope stability analysis and the results are consistent with the actual scene, which show the results of rock-mass damage test accord with the actual project. |
