Pile foundation is a very commonly used in industrial and civil engineering infrastructure.
But it pours rare that platform on piles of the engineering project is built above the protection target and shares the upper-loading.
According to the experience of similar projects in the past, it can be expected that, within 50 years of engineering use fixed number of year, the final settlement of the water pipe will be about 100 mm.
The results are greater than the results calculated by engineering specification method and slightly smaller than the finite element method.

Therefore, “Fire Safety Rules for High-rise Civil Building” states that the following kinds of buildings should be equipped with fire elevator: first-class public building, tower-type apartment building, apartment building with 12 stories or more, gallery apartment building, and second-class public building exceeding 32m.
At present, some engineering projects in China have put this method into practice.
Combustion performance of external-wall insulation materials is a significant criterion to evaluate fireproof and safety performance of civil building, the design and construction of which will directly influence building’s function and safety.
The second article in the “Interim Provisions on External-wall Insulation System and Finishing Fireproofing of Civil Building” formulates that high-rise residential buildings should abide by the following provisions: If the height of the building is no less than 100m, combustion performance of its insulation materials should be A level.

In order to validate the scientific and feasible of the prediction, this paper use BP neural network’s training and testing to deal the date which is from Wuhan-Guangzhou railway passenger special line which the roadbed reinforcement engineering, and then estimate risk analysis the variance of schedule,(It is shown in Table 2, seven sets of data used for network training, the other three groups for network test).

Population density decides the frequency of engineering activity.
Therefore assignment values of engineering activity should be based on population density firstly, and then the distribution of mines is used for adjustment (table 6).
