This special issue of Key Engineering Materials contains selected refereed papers presented at the Sixth International Conference on Advanced Computational Engineering and Experimenting (ACE-X 2012) held at Kalyon Hotel (Istanbul), Turkey during the period 1^st-4^th July, 2012.

Take the specialty of water supply and drainage engineering in USC for example.
Also, we have equipped some English teaching materials.
Then, we improve the teaching materials construction in the way of the combination of introducing and self-editing.
Based on the latest design codes, the two books Building Water & Wastewater Engineering and Fire Engineering, and Modern Water & Wastewater Engineering Design are edited, which analyze many design cases at home and abroad.
Furthermore, in combination with the talents training goals and the latest research achievement, we speed up the process of teaching materials construction, and carefully choose materials and update contents so that the materials can show scientific nature, advancement, theoretic nature and practicality , obey teaching rules and display remarkable regional characteristic.

Theoretical research and engineering practice of soil conditioning and the variation characteristics of key construction parameters based on TBM construction in sand-pebble layer are also very few.
At first, changing single foam to composite foam (SLF30+10%SLFP1); Secondly, adding Rheosoil143 foaming polymer and HHZ-02 dispersive agent; And finally, three materials are mixed in certain proportion and injected into the earth chamber.
So variety of improved materials will achieve multiple functions for soil conditioning in improving plastic flow of soil

The two methods are being used at the macro-level and civil engineering.
Sahely （2005）pointed out it is important to take the system method to define the impact of engineering activity on environment, so that the concept of engineering integrality is put forward.
Key Performance Indicators (KPIs) for Sustainable Infrastructure Key Performance Indicators ( KPIs) for Sustainable infrastructure in China Every type of infrastructure (e.g., communication engineering, pipeline engineering, transportation irrigation engineering) has its characteristics so that the indicator could be researched in two parts, one is the general indicator, and the other is special indicator that can be used to describe the specific principle of the project.
One is to take the civil engineering project as a part of an economic system.
