摘　　要：基于多尺度系统理论和小波变换方法,对在运用TDR技术进行岩土体深部变形监测时得到的复杂多变的反射信号进行分析。根据小波函数的特点,提出复合小波分析方法,通过降低小波函数的计算难度实现TDR监测信号的分析难度与分析时间的减少。工程算例表明,该方法对于处理数据量较大的大型边坡TDR监测信号分析来说具有较高的应用价值。Based on the multi-scale system theory and wavelet transform method,some analysis about reflected signal received by time domain reflective（TDR） monitoring soil and rock deformation were made in this paper.According to the characters of wavelet functions,composite wavelet transform was proposed to reduce the difficulty of analyzing as well as to shorten the time of calculating through lowering the calculation difficulty of the functions.An engineering case showed that this method was effective for large-scale TDR deformation monitoring having larger input data.
