The case study illustrates the potential of the proposed model in engineering application.
Soil failure is an essential topic for engineering purposes.
In many cases, it is enough for engineering purposes to assume n equals 1 or 2.
It is shown how to apply the proposed criterion for actual engineering projects.

Machine Learning Machine learning is a tool that can be used to yield models that help predict the behavior of civil structures.
Within the civil engineering area, there are studies such as those by Huang and Burton [33], who explored the classification of in-plane failure modes for reinforced concrete frames with infills using machine learning, they found that decision tree, random forest and adaptive boosting models were suitable for studying purposes.

Study of the Durability Characteristics of Hydraulic Concrete Xin Gu1, a, Linxiao Ouyang2,b 1School of Civil Engineering, Dalian University of Technology, Liaoning 116024, China 2School of Architecture and Fine Arts , Dalian University of Technology, Liaoning 116024, China amrguxin@163.com, bouyanglinxiao@163.com Keywords: hydraulic concrete; durability; freeze thaw cycle; concrete crack.
In addition to this, hydraulic concrete is also employed in river and harbor engineering, irrigation and drainage engineering, water proofing work and so on.
Because the hydraulic structure works under the condition of still water or movable water, the water infiltration, scour, freeze-thaw cycle, erosion make the service environment of hydraulic structures more severely and harsh comparing to common civil engineering application which puts durability more obvious position.
These findings may be of interest to engineers designing concrete hydraulic structures.

Numerical Simulation Analysis of Temperature Stress of Super-Long Steel Structure Plant Weihua Ma 1,a Qingjuan Meng 1,b Lejie Liang 2,c 1Department of Civil Engineering Tangshan College,Tangshan 063000, China 2Institute of Civil Engineering,Hebei United University,Tangshan 063000, China amwh99@163.com, bmqjmqj2728@126.com, cliang.lejie062@163.com Key words: super-long steel structure,numerical simulation,temperature stress,displacement Abstract.Numerical simulate analyze a super-long steel plant with ANSYS,calculate the structure in expansion joint,without expansion joint and without long circle bore structure of these three kind situations,analyze temperature stress and vertical displacement of the main component when the temperature changes.Setting expansion joint can control the temperature stress in a small range,which is a widely used method at present.However,not setting expansion joint and the use of long hole structure connection can control the size of the temperature
stress and ensure the structure globality,it can provide design basis of this method in engineering applications.
Engineering situation The engineering is a single-layer plant in Tangshan City,Hebei Province,using variable cross-section shaped beams,columns.The vertical length of the plant is 396 meters,the distance of column is 6m and 12m,horizontal length is 90m,divided into three cross equally.The vertical length exceeds the design requirements,for such a large area of plant,we must first solve the problem that how to solve the temperature expansion in the design of the engineering.
The stress of the steel beam, column is very small,generally less than 30MPa.When the temperature falls 30℃, the maximum displacement at the end of the frame vertical is 0.048m, The middle of the two frame departs each other,the total displacement is 0.040m.We can see from the above two extreme temperature,according to the displacement of the two middle frame,setting the size of the long circle bore to 0.080m can meet the engineering requirements.
