fissure fracture

The mechanical property of N80 steel has increased obviously after adding corrosion inhibitor, where the ductility of N80 steel increased, and crack fissure of fracture surface decrease.

添加缓蚀剂后使N80试样的韧性有明显的增加，断口裂纹缝隙明显减小，力学性能有了明显的提高。

Gold mineralization in Jinchang gold deposit is divided into fracture alteration type, fissure filling type and cryptoexplosion breccia type.

金厂金矿金矿化分为构造蚀变岩型、裂隙充填型、隐爆角砾岩型。

Finally, some problems needed for further study are put forward, including the regularity of fissure deformation and fracture under shear loads, the influences of shear loads on fissure permeability under different normal loads, constitutive relationship of fissured rock mass, etc.

指出了需要进一步研究的问题：剪切荷载作用下裂隙变形和破坏规律；不同法向荷载作用下剪切荷载对裂隙渗透性的影响；

Rock mass is discontinuous because of the movement and development of the crust. The joint, fissure, fault fracture are the typical modes of this discontinuation.

岩体介质由于地壳的不断运动、发展，呈现出显著的不连续性，存在大量的节理、裂隙等不连续界面。

Through grouting experiments in a single fissure and fracture networks, the basic law controlling the grouting seepage through rock mass is analyzed, and the factors which may affect the process are also discussed.

通过单一裂隙岩体和裂隙网络岩体注浆渗流模拟实验，分析和总结了裂隙岩体注浆渗流中的一般规律，并讨论了影响注浆渗流工程的各种因素。
