摘要
根据复合支护结构的构造和施作过程的特点,对其分析了承载机理,提出了洞周承载环和高强度抗力点的概念,并在指出喷层与内衬主要承受与围岩变形的依时性特征有关的形变压力和自重荷载的基础上,依据变形协调条件对其建立了设计计算方法.
In this thesis, based on the characteristic of structure and construction process, the mechanism of the com- posite lining is studied, and the conception of opening cireumference bearing ring and high strength resistance forcepoint is raised This paper also points out that the main load of the composite lining is the deformation pressure, whichis related to the time-dependent character of the surrounding rock,then by using the deformation coordination condition, a calculation method which suits composite lining is established.
