| 摘 要： | 利用位移、应力、能量耦合监测技术,分别对渗流大小、沉降量、声发射特征参数等之间的关系进行统计,全面分析渗流对坚硬复合岩体支护的塌陷区围岩结构动力失稳的影响.研究表明, 在渗流的作用下,塌陷区不稳定程度加剧,通过声发射监测特征参数可以初步分析渗流与塌陷区结构失稳之间的演化关系.

| Abstract: | Based on the displacement, stress and energy coupled monitoring technique, the trends of subsidence rate, characteristic parameters of acoustic emission, and seepage in the subsidence area were statistically analyzed, respectively. The seepage influence on structural dynamic damage was evaluated synthetically. The result showed that the deformation rate was accelerating seriously and the evaluative trend between seepage and damage can be simply estimated by acoustic emission monitoring. |

| Keywords: | seepage due to heavy rain structure damage of subsidence area coupled monitoring acous-tic emission |
