The Study of Construction Settlement Observation Wen Yu1, a, Jie Yu2, b , Jianjun Shi3, c 1 Hebei Institute of Architecture and Civil Engineering,Zhangjiakou,China 2 Zhangjiakou Vocational College, China 3 Zhangjiakou Tongtai Holding Company,China ayuwen_2008888@yahoo.com.cn byujie2008yu@sohu.com cshijj1018@163.com Keywords: building engineering; settlement observation; settlement points Abstract.
Settlement observation is an important measurements of construction engineering deformation observation.
For the civil construction, the building settlement observation points should be set at the four corners of the building, big corner of the building and plinth that the distance is about 10 meters to 15 meters.
The Cycle Arrangements of Settlement The cycle and frequency of the construction settlement observation should be according to the properties of engineering, construction schedule, the ground condition and the change of base load conditions.
The settlement observation of the civil building must implement once when the building increased 1~5 layers, thus we can find the relationship between the settlement observation data and the building load, and we can find the uneven settlement at beginning, it is convenient for us to adjust the scheme of the settlement observation.For the reason that the settlement always lag behind the load of the building, there are amounts of settlement during the decoration period.In the mean time, the floor, the lime of the wall and the fixing of the instrument add the building load, and the building load was irregular due to the funds and other elements, so the rate of the settlement are different, we should arrange the settlement observation cycle due to the data of the previous daily average settlement,we do not stop the settlement observation until the settlement stops.

Introduction The stability of elastic columns is of much importance in civil engineering, and mechanical engineering.
In some structures in civil engineering systems such as tall buildings, the effect of axial force induced by gravity cannot be simply neglected.
For structures in building and civil engineering, Blaauwendraad [5] showed that Haringx’s model seriously overestimates the critical loads and Engesser’s model is preferred.

Hybrid joining of structural parts (e.g. [3-16]) is relatively new approach to create more safe and reliable connection of the critical part of engineering structures.
Typical civil airplane reaches 60 000 hours of a lifetime.
They can be applied successfully in the further investigations of complex real engineering structures.

The work of the conference was aimed at providing an opportunity for scientists, graduate students and representatives of the construction industry to generalize the recent achievements results in the field of industrial and civil construction (design, organization of all types of work, construction materials, etc.), discussing promising directions for the construction industry development and establishing useful partner relationships for future interaction.
The conference was held on numerous topics: • Construction mechanics and theory of structures, civil and industrial engineering • Architecture, design, reconstruction and restoration of architectural heritage • Building materials and technologies of binders, concretes and building ceramics • Organization and technology of construction production.
