The problem is simplified as one of a joint under I mode internal pressure in the finite rock mass, and solved by the near-joint-line method based on the failure criterion of rock bridge material and equilibrium equations.
将该问题等效为节理面受一对I型拉力作用的问题,采用节理线附近分析方法,从平衡方程和岩桥材料的破坏准则出发进行求解,得出了节理内压大小与节理扩展长度之间的解析关系。

in the paper, considering of the mechanical behavior and heterogeneity of rock bridges between preexisting echelon cracks in the rock specimen, the characteristics and mechanism of propagation, interaction and coalescence of cracks in the different rock bridge are studied by using RFPA~(2D) (Rock Failure Process Analysis) code newly developed by CRISR, Northeastern University.
通过考虑岩石试样中预置三裂纹之间岩桥力学性质和非均匀程度，运用东北大学开发的ＲＦＰＡ（２Ｄ）系统，研究了不同性质岩 桥中裂纹扩展相互作用模式及其贯通机制。

In this paper, through model test and non liner finite element analysis of direct shear model, sythetic shear strength of shear plane including discontinuity and rock bridge is studied in consideration of various normal stress, rock bridge persistant ratio and rock bridge distribution.
通过直剪模型试验和非线性有限元分析，研究了由结构面和岩桥组成的剪切面在不同法向应力、不同岩桥面积及不同岩桥分布型式等条件下的综合抗剪强度，较客观地评价了岩桥对剪切面抗剪强度指标的影响，初步探讨了岩桥的破坏机理。

2.
This paper shows that it is possible that the sediment of low stand system tract can exist in the basin as the case of Qiaotou sandstone of the upper Taiyuan Formation interprets.
以太原组上部灰岩段中桥头砂岩为例 ,通过对露头、岩心、测井曲线的分析和层序对比以及海平面升降变化对研究区沉积影响的分析 ,认为桥头砂岩形成于不同的三级层序内 ,由 3套低位域下切河谷充填沉积叠置而成 ,说明在盆地内古大陆架上也可以发育低位体系域沉积。
3.
Tectonic disturbance,sea level change and differential compaction provided enough accommodation space for the distribution of K1 sandstone and Qiaotou sandstone.
本溪组—太原组形成于陆表海背景之下,陆表海基底平缓,层序结构大多为二元体系域结构,在构造变动、区域海平面下降及差异性压实作用等因素的控制下形成了以K1砂岩和桥头砂岩为代表的低位体系域河道下切充填。
