摘要
为了研究锚杆在不同自由长度下，支持体结构的温度应力、接触缝面的张开度以及锚杆应力，通过三维有限元法模拟施工过程温度徐变应力的仿真计算，及对砼结构与岩体之间交界面接触问题的非线性分析，解决了锚杆自由长度的合适取值问题。
In order to study the tempereture stresses of supporting structures, the openings between contact surfaces and the anchoring stresses under different free anchor bar lengths, by means of 3D FEM calculation for simulating the tempereture creep stresses in the construction period and nonlinear analyses to the adjacent contact problems between concrete structures and rock mass, the problems for taking proper values of the free lengths of anchor bar may be resolved.
