中文摘要：

根据锚杆与桩的荷载传递过程的相似性,分析群锚荷载传递机理;引入群锚＂加筋＂效应的概念,考虑加筋效应影响下的群锚位移变化规律,建立群锚位移计算基本微分方程,提出了一种新的能更全面考虑锚杆间相互作用的群锚位移计算方法。通过改变锚杆间距、直径、锚固体长度,得到不同参数对群锚位移的影响。最后,采用该位移计算方法对某实验进行分析,分析结果表明,位移计算值与实测值较吻合,且该方法计算工作量小,便于工程应用。

英文摘要：

The load transfer mechanism of anchor groups was analyzed based on the similar load transfer between anchor groups and piles,and the concept of reinforcement effects for anchor groups was introduced.Based on the analysis of displacement behavior considering reinforcement effects,a basic differential equation served as the formula for the displacement calculation of anchor groups was set up,a new calculation method for the displacement calculation of anchor groups was established with a more comprehensive consideration of anchor-anchor interaction.Also via changing anchor intervals,diameters and lengths of anchorage body,the influence of these parameters on the displacement of anchor groups was analyzed.This new method was applied to the analysis of an experiment.The results show that the calculated results are closed to those of the test.This method can be easily applied in the practical engineering and can decrease the cost of calculation.
