During freezing sinking, the displacement and affecting factors of deep alluvium frozen soil wall was a technical problem which need to be resolved.
The factors affecting it such as frozen soil thick, height of deep alluvium, segment height, exposure time and excavated radius were utilized.
The article took the first Chinese design of deep alluvium frozen soil wall over kilometers as background and makes the numerical simulation analysis to the factors concerning the displacement of frozen soil wall, such as the thickness of frozen soil wall, freezing temperature, the excavation high of wellbore, the properties of soil and the exposure time etc. using the frozen soil creep parameters attributed by the finite deformation and using the numerical analysis software of FLAC2D, then compared with the results of actual measurement engineering.
By making regression analysis, obtained the numerical calculation models of freeze wall’s maximum radial displacement considering frozen wall thickness, alluvial soil depth, excavation section high, excavation radius and other factors, which proved the formula rationally through comparing with engineering measurement datas.

Mechanical properties of Al alloys can be greatly enhanced by incorporating reinforcing particles, forming composite.
The most important benefit of this technique is to find out the possible interaction between the factors.
Mechanical and Wear properties The mechanical properties of a composite depend on many factors such type of reinforcement, quantity of reinforcement, shape, size etc.
The author have produced Al (6061-T6)/B4C composite and investigated its mechanical properties.
Applied load is the wear factor that has the highest physical properties as well as statistical influence on the dry sliding wear rate of the composites among the other factors such as sliding speed and sliding distance.

Keywords: subgrade engineering; rock slope; safety factor method; Sarma method
Abstract: A mechanical model for Sarma method was built based on a sliding of simple non-homogeneous rock slope as the research object.
The slope system is a common geomorphologic shape; its stability depends on the physical and mechanical properties and failure modes of geotechnical.
The changing process of instability and failure modes will be affected by the diversity and complexity of the substance of the slope system and will be decided by complex rock structure, geotechnical conditions and the initial stress state.
The mechanical model is shown in Figure 1.
The stick compartmentalization can be distinguished according to the soil properties of the rock mass and actual landslide structural level.

The properties and the performance of Thermally Stable Diamond Composite (TSDC) directly affect the applications of TSDC in engineering.
The failure risk of the TSDC cutting tips during a cutting process is affected by many factors, including the Depth of Cut (DOC) of the pick with the TSDC tip.
The failure risk of the TSDC tips is significantly affected by the various uncertain factors in the mining environment, including the TSDC material properties, TSDC tip shape and size, rock strengths, the angle of resultant force (or simply resultant angle) on the tips and the Depth of Cut (DOC).
DOC and resultant angle of the resultant force are two major factors that directly affect the characteristics of bending force on the tip in the mining and construction industries.
To strength the study, the impact of the uncertainties in other factors will be analyzed in the future.

Predicting the material's mechanical properties is essential for reducing testing time, cost, and effort.
Introduction Aluminum is the most used nonferrous metal in the local and global industries due to its excellent physical properties, and the wide range of mechanical properties that it attains through heat treatment and alloying [1].
Despite the well-defined steps in the T6 treatment, various factors affect the achieved values of mechanical properties such as hardness and impact toughness.
Their result showed that mechanical properties were not affected during artificial ageing by the prior precipitation process.

Effect of different ultrasonication applied on the mechanical properties and morphology of nanocomposites were investigated.
By incorporation of graphene nanoplatelets as fillers in the polymer matrices, significant enhancements had shown in some properties of polymer nanocomposites such as mechanical properties, electrical properties and thermal properties [3].
However, distribution and dispersion of nano-scale fillers in the polymer matrix are the key factors that affect the final properties of nanocomposites.
Result and Discussion Flexural properties.
Conclusion Method B with tip sonication shows greater effects towards mechanical properties of epoxy/graphene nanocomposites.
