Abstract: The paper discussed the problem of disengaging of face slab at face slab rock-fill dams. Because disengaging is random and hidden, it is difficult for traditional single point monitoring to identify. Hence, disengaging monitoring with temperature method was presented here. The monitoring principle of temperature method, the laboratory tests and results were introduced in detail.

摘要： 叙述了面板堆石坝面板脱空问题，由于面板脱空具有隐蔽性和随机性，以往的单点监测法对此很难胜任，因此，提出采用温度法对面板脱空进行事前监测。文中详细介绍了面板脱空温度法监测的方法和原理，以及室内试验情况和试验结果。
