The soil mechanic course acts as a professional basic course of civil engineering.
Introduction The soil mechanics is a professional basic course of civil engineering water, hydraulic engineering and so on, which plays a transitional role between the basal courses and the specialized courses.
The design, construction and use of any civil engineering are related with instruction of soil mechanics theory.
Therefore if the civil engineering specialty and other relevant professional students want to learn their specialized courses well, the soil mechanics is a must mastered important professional basic course.
Some cases in geotechnical engineering.

The aim of this paper is to analyze the suitability of reusing waste (wood ash) resulting from the combustion process at wood product industries for manufacturing cement based materials used in civil engineering.
An alternative approach for reducing the environmental impact caused by the generation of this by-product, i.e., wood ash, would be its use in products for civil engineering [4], an area which requires a high amount of energy and non-renewable raw materials.
However, pozzolanic features may be observed, which explains the use of solid mineral waste in civil engineering [6].
An analysis of wood ash particle size distribution was undertaken in accordance with specific parameters set for grain size classification of sand for civil engineering.

Numerical simulations recently conducted by the authors have verified that the smart passive system could be effective to reduce the structural responses in the cases of civil engineering structures such as buildings and bridges.
MR damper-based smart damping systems are mainly applied to reduce the excessive vibration of large-scale structures such as high-rise buildings and long-span bridges in the field of civil engineering [1-3].
Experimental Test of Large-scale EMI System The experimental test of the large-scale EMI system is carried out to verify its feasibility to real-scale civil engineering structures by using a shaking table system.
Therefore, the large-scale smart passive system could be considered as one promising control devices for civil engineering applications.
However, more detailed experimental tests should be carried out to more clearly verify the applicability to full-scale civil engineering structures and are now on progress.

The above numerical results offer us some theoretical indications and instructions to further investigate the instability failure mechanisms of engineering concrete structures in civil and hydraulic engineering.
This has been observed in laboratory tests and in situ monitoring of existing geotechnical and civil engineering structures.
It is indicative for us to gain an insight into the nature of the micro-fracturing process and the mechanisms of the creep instability failure mechanisms of engineering concrete structures in civil and hydraulic engineering.
