预应力锚索群锚锚固边坡均质岩体的室内模型试验研究

为研究预应力锚索群锚锚固实体均质岩体边坡的群锚效应及锚索的布置方案,针对预应力群锚锚索锚固后的边坡均质岩体进行了室内模型试验。根据多种群锚方案试件的试验结果,研究了预应力群锚锚索锚固均质岩体模型的强度变形特征。通过试验中不同间距群锚中的单锚对模型试件强度变形的不同影响,研究了模型试件中所体现出的群锚效应。最后得出了与群锚效应相关的可供工程参考的相关结论。

Laboratory model test investigation of prestressed anchor cable group strengthened slope intact rock

It is necessary to research the anchor cable group effect and anchor cable's layout scheme in the intact rock slope. Pointed to the slope intact rock strengthened by the prestressed anchor cable group, laboratory model test was preceded. According to the different results of different space length of the anchor cable group model specimens,strength and deformation properties of the model were investigated. According to the different strength and deformation influence caused by every single model anchor cable material in every different space length anchor cable group model specimen, the manifest anchor group effect was investigated at the same time. The investigation result was returned to the practice. Finally,conclusions about anchor group effect and anchor cable's layout scheme were drawn and can be referenced by the intact rock slope engineering.
