| 摘 要： | 对会昌台数字化洞体形变观测资料的干扰因素进行了分析。分析结果表明,会昌台大多数洞体形变观测资料稳定可靠,年变动态清晰,受气象因素影响不大,形变与洞温相关性较好,年变受控于洞温变化。雷电击坏仪器导致断记是影响连续率的主要因素,更换仪器可能对形变的趋势变化造成一定影响。

| Abstract: | In this paper,the disturbance of digital deformation observation data of Huichang cave is analyzed.The result shows that most of the deformation observation data are stable and reliable;the annual dynamic variations is clear;it is less affected by the meteorological factors and good correlation with cavity temperature,and the annual dynamic variations are mainly controlled by cave emperature.The main factor affecting the continuity is the lightning strike instrument.The replacement of the instrument may have a certain effect on the change of the deformation trend. |
