| 摘 要： | 岩体声发射检测技术是岩质工程结构受力破坏的实时动态检测方法，声发射信号参数与岩质工程结构受力产生破裂损伤或破坏紧密关联，具有 一个测点监控范围大，实时提供信息等突出优点。永久船闸边坡稳定性声发射监测实现了对边坡岩体全天候自动化连续监测与数据处理。根据声发射数据的变化及“突变”，对边坡岩体稳定性及其发展趋势进行评价，并为船闸边坡岩体受力损伤开裂部位的加固，及时地提供了有效依据。

| Abstract: | The acoustic emission(AE)monitoring is a real-time technique of inspecting failure of rocky engineering structures.AE signal parameters depend tightly on the damage degree of structures.The method has some advantages such as extensive inspecting range and real-time collection of information.An all-weather automatic inspecting and data processing was realized for monitoring of the stability on the high slopes of the Three Gorges permanent shiplock by the AE technique.According to change and jump of AE frequency data,stability and developing trend of the slopes were evaluated,and the results can be regarded as grounds of reinforcement of rock mass of the slopes. |

| Keywords: | AE monitoring frequency data high slope stability |
