采场围岩整体结构与砌体梁力学模型

Solid structure and model of voussoir beam of face surrounding rock

本文是近两年来深入开展砌体梁理论研究的总结，并提出了把采场围岩作为一个有机的整体，在围岩运动中起骨架作用的结构可视为砌体梁。在围岩整体结构思想前提下分析了采场底板破坏与突水，岩层移动与离层，砌体梁结构的受力与关键块体的稳定，砌体梁结构的Ｓ—Ｒ稳定性等矿压机理。

his paper is the summary of deeply researching the voussoir beam theory recentyears,proposing that the face surrounding rockmay be considered as an organic whole,and at surrounding rock moving the structure acting asframe may be regarded as the voussoir beam. Under the premise of solid structure,themechanism of undgound pressure,such as the face floor damage and flash flood,the strata movement and separation layerm the acted force of the structure of voussoir and the stable of the key block, and the stability of S R of voussoir beam structure, were analyzed.
