joint fissure

Hydrocarbon and water spill into the reservoirs in the mixing pattern through pore, fracture and joint fissure.

油气水以混相涌流方式为主，孔隙、微裂隙和微层理面是油气运移的通道；

Main research work and results are as fllows: ( 1) The distribution rules and damage modes of the joint fissure are researched based on the survey data of the deep slope in JDC open pit.

通过对金堆城露天矿深凹边坡各帮松动岩体节理裂隙调查，研究了其产状分布规律和破坏模式。

It was difficult and worst risk that tunnel anchorage compound with prestressed anchorage cable was designed and constructed in engineering boundary condition with abundant joint fissure or break ground, the research was blank both domestic and abroad.

在节理裂隙发育或破碎岩层的工程边界进行悬索桥带预应力岩锚的隧道式复合锚碇工程的设计和施工，其难度和风险极大，国内外的研究基本处于空白。
