| 摘 要： | 岩石工程系统的破坏发生在系统相对最薄弱部位和环节，系统的弱场控制着岩石工程的承载力。在建立弱场控制概念的基础上，提出了强度问题的弱场控制原理及其发生判据，利用数值分析和红外监测实验相结合的研究方法，探讨了含梯形孔洞混凝土试件弱场控制的演化过程及对应的破坏现象，证实岩石工程系统的弱场是岩石结构与外力相互作用的结果，弱场是岩石工程系统破坏的控制区域。

| Abstract: | The rock engineering system's failure occurs in the relatively-weak parts and taches.The system's weak-fields controls the bearing capacity of the rock engineering.Based on establishing the concept of weak-field control,the weak-field control principle and occurrence judging criteria are put forward in this paper.With the research method combining numerical analysis with infrared monitoring experiments,the evolution process and corresponding failure phenomena of the concrete sample's weak-fields control including trapezium-hole are discussed.It is verified that the rock engineering system's weak-fields are the mutual interaction result of the rock structure and outside force,that the weak-field is the control range of the rock engineering system failure. |
