锚杆劈裂注浆试验研究

Testing study on the anchor established by fracture grouting

在可行性研究的基础上， 进行了一系列现场试验． 试验结果表明： 劈裂注浆不但增加锚固段的体积与表面积， 而且还强化了锚固段周围土体的力学特性． 因此， 劈裂注浆可大幅度提高锚杆的承载力．

Based on the feasibility study, a series of experiments have been conducted in situ on the anchor established by fracture grouting. The results show that the fracture grouting not only increased the volume and the surface area of a fixed anchor length,but also strengthened the mechanical characteristics of the soil around the anchor. Therefore fracture grouting greatly increased the bearing capacity of anchor.
