中文摘要：
在岩土工程中施加各类加固锚件以改善岩体工作条件、提高岩体的稳定性已成为岩体施工中增稳的主要措施.研究了全灌浆岩锚的锚固特性.应用Mindlin问题的位移解和有限差分法研究了基于抗拔作用的拉力型和压力型锚杆荷载传递机理,利用差分法推导了锚固体与岩体之间的剪应力沿锚固长度分布规律的计算式,通过算例分析了锚固体轴力及其表面剪应力沿锚固体长度的分布规律及其影响因素,为岩土工程锚固的进一步分析和设计提供理论依据.
英文摘要：
In order to improve the working condition and stability of rock mass, it has become the a most frequently used measurement to apply various reinforcement anchor in geotechnical engineering. The bolting character of full grouting rock bolt was studied. The load transfer mechanism of tensioned grout anchor and pressured grout anchor was analyzed based on Mindlin＇s solution of displacement and finite difference method. The distribution of shear stress between bolt-grouting body and rock-body along the anchoring length are deduced based on finite difference method. The influential factors of the distribution of bolt-grouting body shear stress and axial force were analyzed.
