The dynamic analysis of the 750Kw wind turbine blade was presented based on Reverse Engineering.
In actual engineering, the damping has little effect on nature frequency and vibration shape, so we usually do not consider the damping when discussing the inherent characteristic of structure.
Blade material is GFRP (glass fiber reinforced plastics).
In reversing engineering, cloud data acquisition is crucial first step.

Combining characteristics of pipe-jacking tunnel, this paper analyzed key-points of construction technology and engineering troubles which occurrence possibly in construction, and introduced some treatment measures.
There are kinds of materials of pipe jacking tunnel, such as steel pipe, ductile iron pipe, FRPM, vitified clay pipe, PVC pipe, asbestos cement pipe and concrete pipe.
Features of pipe jacking tunnel project Compared with ordinary civil engineering project, the pipe jacking tunnel has its own features as follows: The equipments are appropriative and the project is relying on the equipment.
So the risk of pipe jacking tunneling is higher than ordinary civil engineering project and demands the technicians to have the merits of being good at sum-up, mastering advanced technology and predicting possible troubles to avoid accidents and risks.

Effects of the addition amount of silica aerogels on mechanical properties and microstructure of insulating materials Lin Maa, Jiabin Wangb, Guiyan Xinc and Qiyao Shed School of Material Science and Engineering, Xi’an University of Architecture and Technology, Xi’an 710055, China amalin@xauat.edu.cn,blty20020931@163.com,cbobby_200x@163.com, dshe3204111@126.com Key words: Silica aerogels; Microsilica; Quartz fiber; Insulating materials; Mechanical property Abstract：Insulating materials were prepared by microsilica, silica aerogels and quartz fibers as raw materials, water glass as binder, and molded by the semi-dry method.
Silica aerogels, as the one of raw materials, can significantly increase the content of mesopores and reduce the thermal conductivity of the materials.
In this study, we prepared insulating materials, with mesopores contained and quartz fiber reinforced, by microsilica, silica aerogels and quartz fibers as raw materials.
Experiment Raw materials Microsilica (95.5%) was provided by Elkem Silica Materials (Kristiansand, Norway).
Conclusions Insulating materials, with the best properties in present study, could be prepared by microsilica, silica aerogels and quartz fiber as raw materials.

The core idea of LC is that in ensuring the quality and safety conditions strive to achieve zero waste, zero failures, zero defects, zero inventory, and strive to achieve the shortest period and a minimum consumption of resources, to achieve the goal of the wasting minimization, customer value (or engineering value) maximization.
From the overall perspective of LC techniques and methods, this article explores the key factors that affect the implementation of LC.
To this end, according to the actual situation in the construction process of the construction project, through project management expert interviews and field research in the construction site, summarizes the key factors in the implementation of LC, they are: weekly Percent Plan Complete(PPC ); grassroots manager (foreman) participate in weekly work plan; according to the completion of weekly work plan to adjust monthly plans; Public announcement tasks standards; schedule, quality and safety information publicly posted; each foreman (employees) signed undertaking to fulfill tasks; meet every morning to discuss yesterday's work and arrange work today; weekly meetings of grassroots managers to discuss the problems of last week working to arrange next week; construction links closely coordinated, and no waiting between them, also no extra processing; constraint management of the construction process in a variety of specifications and requirements; materials, manpower, equipment at the stipulated
In surveyed project, civil engineering projects accounted for 55%, industrial construction projects accounted for 12% , the municipal utility industry construction projects accounted for 17%, and 16% of other types of projects.
