中文摘要：
为研究岩体加锚的物理效应，将被全长粘结锚杆加固的岩体当作一复合体，根据其受力后变形的特点，利用弹性力学理论推导了该复合体在锚杆的轴向和垂直锚杆轴向的弹性模量，并利用界面元法进行了数值计算。理论分析和数值计算均表明，加锚能提高岩体的弹性模量。通过对这两种方法计算结果的比较分析，给出了实用的简化计算公式。
英文摘要：
The physical and mechanical effects of rockmass anchoring are very obvious. The rockmass strengthened by full length grouted bolt is regarded as a composite body and according to its deformation characteristics when it is stressed, the composite elastic modulus along bolt axial direction and vertical to the bolt axle is deduced by elastic mechanical theory, which is compared with the result obtained by numerical analysis. On this basis, a practical simplified algorithm is given.
