Evidently, the deformation is a kind of time-dependentdeformation caused by underground mining.
显然，这是地下采掘引起的表生时效变形。

The approach based on wavelet theory and phase space reconstruction for analyzing the law of time-dependentdeformation of crack according to the observation data of dam is proposed.
本文基于小波分析理论和相空间重构技术，根据大坝裂缝的实测资料，提出了裂缝时变规律分析方法。

Because the viscous coefficients of the dam and foundation rock are great, the time-dependentdeformation caused by the dam self-weight leads to the dam upstream deformation stabilize in a long time;
