本文讨论了收敛-约束法在满足Hoek-Brown破坏准则的岩体中的实际应用。回顾了Hoek-Brown准则定义的完整岩体和节理岩体的强度，以及收敛约束法的基础。给出了收敛约束法的三个基本组成部分的方程，即：i）纵向变形剖面（LDP），ii）地面反力曲线（CRC）和iii）支撑特征曲线（SCC）。本文讨论了圆形隧道支护设计的一个实例，并用收敛约束法进行了求解。还包括一个总结该方法实施情况的电子表格。典型岩石特性和典型支护系统的几何和力学特性的参考值以表格和图表的形式给出。(C)2000由爱思唯尔科学有限公司出版。版权所有。
This paper discusses the practical application of the Convergence-Confinement Method of tunnel design to rock-masses that satisfy the Hoek-Brown failure criterion. The strength of intact rock and jointed rock-masses, as defined by the Hoek-Brown criterion, and the basis of the Convergence-Confinement method are reviewed. Equations that allow the construction of the three basic components of the Convergence-Confinement method, i) the Longitudinal Deformation Profile (LDP), ii) the Ground Reaction Curve (CRC) and iii) the Support Characteristic Curve (SCC) are given. A practical case of support design for a circular tunnel is discussed and solved using the Convergence Confinement method. A spreadsheet summarizing the implementation of the method is also included. Reference values of typical rock properties and geometrical and mechanical properties for typical support systems are presented in tables and charts. (C) 2000 Published by Elsevier Science Ltd.
