Study on the settlement of soft soil subgrade with a crust layer Dazhi Wu1, a, Zhenying Zhang1,b 1School of Civil Engineering and Architecture, Zhejiang Sci-Tech University, Hangzhou 310018, P.R.
Due to the long-term effects of water evaporation, lowering of groundwater level, load transfer, the precipitation of soluble salt and other ingredients, and some other factors, a thin layer with good engineering properties can be formed at the surface of the soft soil, this is the so-called crust layer [1, 2].

The Comparison of Two Methods on the Reliability of Ship Collision for Bridge Based on Applied Mechanics Longsheng Bao1, a, Jun Zhang1, b, Ling Yu1, c, Guangshan Zhu1, d 1College of Civil Engineering, Shenyang Jianzhu University, Shenyang, Liaoning, 110168, China abaolongsheng710605@163.com, bzhangjun19870510@yahoo.com.cn, cyulingsy@163.com, dcegszhu@sjzu.edu.cn Key words：The reliability analysis of ship-bridge collision; ANSYS; Response Surface Method; BOX-BEHNKEN; Monte-Carlo method Abstract: As for the reliability of ship-bridge collision, function relation between the structure response variable and basic variable is very complex and the traditional theory has been difficult to work it out, so we need the help of finite element numerical method to obtain the solution.
The sampling of Monte-Carlo method is classified into three kinds, respectively Latin Hypercube Sampling, Direct Monte-Carlo Sampling, from the User-Defined Sampling, among which the Latin Hypercube Sampling avoids the direct method of repeated sampling and improves the engineering calculation efficiency.
Conclusions (1) In the practical engineering structure reliability calculation, when the structure of the failure probability is less than , the traditional Monte Carlo method sampling frequency is very large, occuping a very large computing time.
In some large complex for calculating reliability engineering, the response surface function is obtained by sampling analysis on structure, it can reflect the basic characteristics of the structure, it is of high precision, and, in some circumstances, the reliability of ODRSM-MCS even more accurate than the MSC.
