Research on deformation prediction of foundation pit braced by complicate soil nailing Pan XIE 1, a 1 College of Water Conservancy and Civil Engineering, South China Agriculture University, Guangzhou, Guangdong, China axiepan@scau.edu.cn Keywords: Grey system theory, deformation, complicate soil nailing, foundation pit Abstract.
In Addition, through theoretical analysis and engineering practical example, the method is proved feasible.
As an efficient, convenient and cheap technique, complicate soil nailing technique is widely applied in the foundation pit engineering at present.
Though there are a large amount of engineering examples of complicate soil nailing, the prediction effect of probability and statistics theory and fuzzy mathematic are undesired because the same complicate form are still lack at the same condition what means historical and statistical discipline and experiential data are absent.

He Manchao [3] established the concept system of the deep engineering , and pointed out that the mechanical system of engineering rock mass in deep which is no longer linear mechanical system which is belonged to shallow engineering, it is the nonlinear mechanical systems.
The traditional theory, method and technology are almost entirely or partially invalid to the deep engineering.
The coefficient of difficulty and risk index would be used as the index to evaluate the engineering rock stability of deep engineering, and this can reflect the mechanical characteristics and engineering properties of deep rock engineering.

The finite element analysis of overall stability of high-frequency welded H-section steel beam Wei Liu1,a, Jun-ping Wang2,b, Yi-sheng Li3,c, Jian-ming Shen4,d 1,2,3,4 Department of Civil Engineering, Faculty of Civil Engineering & Architecture, Kunming University of Science & Technology, Kunming 650500,China a417796968@qq.com,bwang264@yahoo.com.cn,c261524836@qq.com,d370701878@qq.com Keywords: High-frequency welded H-section; Linear-FEM; Critical stress; Overall stability factors Abstract The width-thickness ratio of high-frequency welded H-section steel beam overruns the limit of the current specification, which is bound to affect the overall stability of the structure.
The counting methods of overall stability factors in the Code cannot be completely suitable for high-frequency welded H-section, so in actual engineering, the applicable scope of the formula in the Code must be considered. 2.
In actual engineering, the crosswise distribution load-condition is very common, and the overall stability factors of the high-frequency welded H-section steel beam which calculated by formula and ANSYS are very similar, the the formula of Code can be directly applied. 5.
The results for different relative slenderness ratios, load conditions, spans, and with two conditions were carried on the contrast analysis in this paper, which could give some advices for the engineering designers.
