| 摘 要： | 坝体、坝基中的渗流观测点所观测的仅仅是该测点及其附近部位的渗流状况,并不能很好地反映作为空间场形式存在的大坝整体渗流,因此,以渗流水头监测量为研究对象,分别考虑本体和层面水压分量的影响,建立能综合反映大坝渗流空间特性的碾压混凝土坝空间渗流安全监控模型.通过实例证明,该模型具有较高的精度,对碾压混凝土坝渗流监控和预警都有重要的意义.

| Abstract: | What is observed from the seepage observation point of the dam itself and the dam base is merely the seepage situation near the observation point,so it can not reflect the whole seepage status as spatial field.We take monitoring quantities of seepage head as the study object,consider the influence of hydraulic pressure of dam body and its dimensions,respectively,and establish a space monitoring model for seepage safety of the roller compacted concrete dam which can comprehensively reflect space seepage characteristics.The experiments indicate that this model has comparatively higher accuracy,which is of great significance for real-time monitoring and early warning for seepage of the roller compacted concrete dam. |
