A test apparatus was developed to study shear-flow coupling properties for a marble fracture with sand.
The hydraulic properties of rock fractures are affected by many factors, such as normal and shear stresses, normal and shear displacements and geometrical parameters of fracture surfaces.
The results revealed that both shear stress and displacement applied on a fracture with sand can produce influence on hydromechanical properties.
There are great differences between shear-flow coupling properties of a rough fracture and those of a fracture with sand.
Development of a shear-flow test apparatus and determination of coupled properties for a single rock joint.

Analysis of Influence Factors for White Layer in Grinding of Harden Steel Xiangming Huang 1,a, Zhixiong Zhou1,b, Yang Jun 1 and Qilong Xia1 1 College of Mechanical and Vehicle Engineering, Hunan University, Changsha, China, 410082 ah_xiangming@yahoo.com.cn, bzhouzx@sina.com Keywords: Grinding process, White layer, Harden Steel, Influence factors Abstract.
Thus, white layer formation is one of factors that affect product performance.
Some studies have shown that process parameters affect the formation of white layer.
Eda [6] studied white layer properties on a machined surface of harden steel when a large depth of cut and higher feed speed were used.
However, the above studies concentrated on the properties of white layer and the formation mechanism of ground white layers, a systematical analysis of the effect of grinding parameters on white layer has not been carried out.

Factors of the design, the construction, the train load and the service environment lead to the wide juncture cracking.
Theoretical analysis was made on the influence of the depth and the length of the cracking on mechanical properties of the CRTS Ⅱ slab track.
Computational model and Parameters Computational model According to the structural and mechanical characteristics of the ballastless track, models usually established are mechanical models on the elastic foundation, such as the model of composite beams, the beam-plate model and the beam-solid model.
In this paper, the wide juncture cracking and the tensile stress of the slab track were the main factors to taken in considered, so a positive temperature gradient of 50℃/m was taken[6].
On this occasion, the damage of the crack of the wide juncture cracking has affected the quality of ballastless track
