摘要
在Mindlin问题位移解的基础上,导出了拉力型锚杆受力的弹性解,分析了拉力型锚杆的受力特征,提出了确定拉力型锚杆支护长度的方法,计算了锚杆在不同岩体中的有效锚固长度,并对影响锚杆有效锚固长度的因素进行了分析,从而为岩土工程锚杆设计提供了一种参考依据。
Based on Mindlin's solution of displacement, an elastic solution of stretched bolts is derived. The mechanical characteristics of the stretched bolts are analyzed and a method for calculating support length of stretched bolts is obtained. The effective length of bolt support is calculated for different rocks. Some factors affecting effective length of bolt support are analyzed. A reference principle for design of bolts is provided for projects.
