链子崖T_（11）—T_（12）缝段危岩体开裂变形机制
|
摘要
文章全面描述了链子崖Ｔ（１１）—Ｔ（１２）缝段危岩体的开裂形变特征，探讨了危岩体形成的影响因素，如重力、煤层采空区、降雨、水库蓄水、勘探掘进和地震等，指出其破坏机理是重力主导下的不对称的压力拱与悬臂梁（板）弯矩的联合作用。危岩体可以分成具有不同稳定程度的若干块体，治理工程也应针对它们的不同特点而设计。
This paper is described main characteristics of deforming-cracking on the segment of cracks T(11)-T(12) of Lianzi cliff dangerous rock body, discussed a series of factors,such as gravity. coal mined-out area. rainfall, reservoir storing, exploring or driving andearthquakes on forming the dangerous rock body: its destructive mechanism is recognizedin the non-symmetry stress distribution in an arched shape of east-west direction and flexing moments of cantilever beam (plate) are induced by gravity of rock body and coalmined-out area. The dangerous rock body can be devided into a few parts, and anchoringengineering has to be designed to fit the features of these parts respectively.
