The measuring equipment and methods for foundation holes have mature application in the industry and civil building sector, which are mainly divided into two categories, contact and non-contact measurements.
As for inspection of foundation holes in industry and civil building sector, different methods will be used under different environmental conditions.
The heavy excavation, digging excavation, cast-in-place pile foundation, disk pile foundation and the like in the industry and civil building sector are all applied in a similar way in the industry and civil building sector, and corresponding inspection equipment or methods are adopted.
The inspection methods of drilling holes in power transmission line foundations shall be proposed by drawing lessons from experience in the industry and civil building sector (contact and non-contact).

Analysis of Parameters Influence on Structure of Continuous Curved Bridge Xiang GU1,a, Shang-ying XIE1,b,Shao-min JIA1,c 1School of Civil Engineering,Southwest Jiaotong University,Chengdu 610031,Sichuan,China aguxiang_x@163.com, bjdtm@jdtm.com.cn, cjiashaomin1@163.com Keywords: curved bridge;long span;small radius;finite element;steel box girder;parameter Abstract.
In the modern urban bridge projects,especially the urban interchange projects and the urban viaduct projects,the long-span curved bridge with the small radius is often inevitably used,considering the transportation under bridges,pipelines and aesthetic factors.This kind of long-span curved bridge with small radius was adopted on the south of Second Ring Road in Chendu of the project of “Two Expressways,Two Extended Roads,Two Ring Roads”.The influence,which the change of the parameters on the structure had,was analyzed by using the finite element software of Midas Civil 2010.Then,the parameter which had greatest impact on the inner force of the structure was found.The girder depth is the key parameter in design.
Fig.1 Horizontal plane of the bridge Fig.2 The section of the girder The Finite Element Model In general,the correctness of the establishment of the finite element model affect the error of the results directly.In the whole bridge structure calculation and analysis of modeling process,the following principles should be considered. 1) The requirement of structure shape change 2) The requirement of material characteristic change 3) The requirement of unit which link others characteristic change 4) The requirement of modeling the dead or live load 5) The requirement of the problem solving accuracy 6) The requirement of the convergence of solution (1)Based on the six requirements above,the finite element model was established by the finite element software of Midas Civil 2010.The boundaries were simulated accurately by adjusting direction of the local coordinates of nodes.Fig.3 shows the finite element model.
According to the most unfavorable load combination which was generated by Midas Civil 2010,it was adopted,which is “dead load+live load+support settlement+heating system+positive temperature gradient”.Table 1 shows the change of the parameters.

For a long time, Filling Wall is widely used in multi-storey buildings and Civil Construction Structures, for its flexible architecture flats and large interior space, etc.
However, because of the imperfection in analysis methods and the defects in model, pure- framework design is used in civil architectures, and the weight of filling wall is calculated by converting to the Line Load on the beam.

The scope of civil aviation transportation ranges from ground to upper air, which the impact of emission varies at the vertical geographical altitude.
Introduction Civil aviation transportation plays a substantial role in China’s economic growth in the last decade.
Model based on International Civil Aviation Organization (ICAO) Landing-takeoff operation (LTO), model based on Environmental Protection Agency (EPA), and SAGE model based on Federal Aviation Administration (FAA).
The US FAA has developed the System for assessing Aviation’s Global Emissions (SAGE) [5] used to calculate and predict aircraft emissions to generate inventories of fuel burn and emissions of CO, HC, and NOx for the total commercial civil flights process.
