【摘要】 围岩变形量测是地下工程监控的主要内容.得到的变形曲线不仅记录了地下工程开挖后渐趋稳定或失稳的过程,而且反映了其瞬时特性,论文通过对变形曲线的分析,提出了研究围岩变形形态的特征值法;在大量实测资料基础上,介绍了特征值法在围岩变形形态分类中的应用。图5,表2,参6。更多还原

【Abstract】 Obtained from measurement of rock deformation that is main content of monitoring stability of underground structures, the deformation curves reflect course and instantaneous characteristics of underground structure becoming stable or instable gradually since it has been driven. By means of analyzing the deformation curves the authors propose characteristic value method which is used to study the classification of deformation pattern on the basis of measured data. 5figs., 2tabs., 6refs.更多还原
