土层锚杆劈裂注浆作用机理的分析

文章分析了影响土层锚杆承载力发挥的因素和劈裂注浆作用机理，完成了劈裂注浆作业参数的计算推导，并在此基础上，进行了岩石锚杆劈裂注浆的压力计算。劈裂注浆不但可增加锚固段的体积与表面积，改善锚固段周围土体的力学特性，还可以大幅度提高锚杆的承载力。

Mechanics Analysis on Soil Layer Anchor by Splitting Grouting

In this paper,factors exerting influences on beating capacity and working mechanism of split- ring grouting have been analyzed for the soil layer anchor pole,and deducing of calculation parameter is completed for splitting grouting.Based on this,press calculation of splitting crack grout for rock layer anchor pole is done,which shows that the splitting grouting not only increases the volume and the surface area of anchoring length,but also improves the mechanical characteristics of the soil around the anchor,besides, greatly increasing the bearing capacity of anchor.
