These challenges have encouraged the researchers and engineers to look for better innovative solutions.
Third, the paper will provide the economic, environmental and engineering implication of these new evolving strategies.
Shearing force activities that occur in fully saturated sandy grounds under moderate to strong earthquake motions may cause certain dangerous effects on civil structures [14].
The response of soil during earthquakes is one of the most important and challenging areas of earthquake engineering.

At last, the approach is exemplified by fuel system of aircraft to demonstrate the applicability and versatility, which explores the engineering research for the analysis technology for safety of the complex system.

The direct solution on normal water depth of I type horseshoe tunnel with flat–bottom Hui Wena, Fengling Lib Department of architecture and civil engineering , Huizhou University , Huizhou, Guangdong, 516007, China awenhui-hzu@163.com, bmmlflmm@163.com Key words: I type horseshoe cross-section with flat–bottom; normal water depth; direct calculation formula Abstract: I type horseshoe with flat–bottom evolved from standard I type horseshoe cross-section.
It is commonly applied in the field of hydroelectric engineering.
The formula is simply and the maximum error is less than 0.3% under the general engineering design range (ratio of normal water depth and arch radius is between 0 to 1.4471). it can be used on the engineering designing practice and the edit of the handbook of hydraulic structure design.
Within the suitable range of the engineering, the absolute maximum relative error of the new formula is 0.3%.
It can satisfy the demand of practical engineering.

High temperature, low temperature, water stability and fatigue test were done for three types of modified asphalt mixture of intermediate course used in high-grade highway engineering in Northeast region.
Bending creep test methods were done according to “Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering” JTG E20-2011T0728.
Water Stability Test Freeze-thaw splitting test was done according to “Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering” JTG E20-2011T0729.The test results are shown in Table 4.
Summary By analysis and comparison of high temperature, low temperature, water stability and fatigue performance of three types of modified asphalt mixture used for intermediate course of highway engineering in Northeast area, Grading GLAC-20 mixture design scheme is recommended for intermediate course, which can be reference for engineering.

A DFSS methodology* Cai Xianxin1, a, Luo Xinxing 2 and Wang Guangsheng 1 1 China Aviation Powerplant Research Institute, Zhuzhou, China 412002 2Business School of central south University, Changsha China 410083 anewnewice@sina.com Keywords: DFSS, methodology, system engineering, MDO, uncertainty.
From the view point of systems engineering which seeks to optimize the overall system functions and to achieve maximum compatibility of its parts, a new DFSS methodology DAMV (Define, Analyze, MDO, Verify) is proposed here into which multidisciplinary design optimization (MDO) [7] was incorporated so as to make DFSS a more powerful tool for the design of complicated multidisciplinary systems.
