摘要
通过测试岩体灌浆前纵波波速及灌浆后纵波波速,可知固结灌浆处理后,岩体内纵波波速大幅度提高,证明在大规模灌浆处理后岩体的变形模量值及承载力将比灌浆试验时有相当程度的提高。
Through testing prefoward wave speed and post grouting wave speed of the rock,the paper finds out that the vertical wave speed has been greatly improved after consolidated.It proves that large-scale post-grouting rock deformation modulus and bearing capacity has been relatively improved comparing to that of the grouting experiment.
