Based on the regional topography, engineering geology, hydrology, vegetation, soil, and soil erosion survey of Xiaolongtan power plant, this paper will analyze the area of influence according to the soil and water loss and its effects in this project, and according to the characteristics of construction projects and the local natural conditions, combined with the characteristics of soil and water loss control degree of each region and the affected, The biological measures with engineering measures together, take slag retaining engineering, drainage engineering, land consolidation engineering and plant measures for the comprehensive management.So the effect of soil erosion will be reduced to minimum level, the area of new erosion will be effectively controlled.
In the period of the 3rd expanding project of Xiaolongtan power plant, the area of soil and water loss caused by construction may include engineering excavation area, ash field area and construction area.
In the site are, after the execution of engineering projects and biological measures for soil and water conservation, the ground slope, land cover could basically meet the requirements of soil and water conservation.
Prevention measures According to the characteristics of construction projects and the local natural conditions, combined with the characteristics of soil and water loss control degree of each region and the affected, In the guidance of soil and water conservation principle and control scheme of soil erosion control, in accordance with the "suit one's measures to local conditions, comprehensive prevention and control" approach, The biological measures with engineering measures together, take slag retaining engineering, drainage engineering, land consolidation engineering and plant measures for the comprehensive management.
After civil engineering is completed, immediately site is cleaning, greening, The focus is all kinds of excavation surface and the construction site.

Introduction Structural Health Monitoring (SHM) is important in many areas of aerospace, civil and mechanical engineering to ensure structural integrity and safety.
The ability to monitor a structure and detect damage at the earliest possible stage has always been of interest throughout civil, mechanical and aerospace engineering.
In civil engineering, there is now a very ageing infrastructure and with bridges and highways required to take ever increasing payloads it is essential to be able to monitor and assess damage in order to aid maintenance strategies and to provide accurate remaining life predictions.

Comparison between the Use of Aluminum and Composites in the Design of a Wing-Spar of An Airplane Mohamed Khamesa, Ahmed Embaby b, and Abdelrahman Aghac Aeronautical Engineering Department, Military Technical College, Cairo, Egypt.
Nowadays, a process of using composites on a large scale to the aircrafts’ construction, in both, the civil and military aviation, was initiated.
In civil aviation, using composite materials allowed us to carry more passengers and cargo (an example for a structure in 50% is made of composites is the cutting-edge passenger aircraft Boeing 787 Dreamliner).
