| 摘 要： | 工程建设中,常在自然山地上开切人工边坡,一旦滑坡将造成巨大损失.实践表明:声发射(AE)技术能有效捕捉滑坡的前兆,从而进行预报.岩体AE检测技术是岩质工程结构受力破坏的实时动态检测方法,具有测点监控范围大,实时提供信息等优点.AE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.某永久船闸边坡稳定性AE监测的实践表明,根据AE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是有效的.

| Abstract: | The AE detection technique of rocks is an on-line dynamic detection method for rock engineering projects when the stress is damaged.The AE signal parameter is closely related to the failure,fracture or damage of the stress of rock structure,and it has dominant advantages such as wide monitoring extent,live information.All-weather automatic continuous monitoring and data processing for the ship lock have been achieved for AE monitoring of the slope stability of the permanent ship lock of the project dam.Based on the variation of AE data and "discontinuity",the stability of slope rock and its development tendency can be evaluated.It also affords timely effective basis for consolidation of the portion of the slope rocks of fractured and damaged stress for the ship lock. |
