Mechanical Characteristics Analysis of Type ∏ Terminal Restricted Configuration Transition Section for CRTSⅡ Slab Track Xiaoping GONG1,2,a, Hong XIAO1,2,b 1School of Civil Engineering, Beijing Jiaotong University, Beijing 100044, China 2MOE Key Laboratory of High-speed Railway Engineering, Southwest Jiaotong University, Chengdu 610031, China a10121413@bjtu.edu.cn, bxiaoh@bjtu.edu.cn Keywords: CRTSⅡSlab Track, Type ∏ Terminal Restricted Configuration, Transition Section, Anchorage Structure, Mechanical Analysis Abstract:With full-bridge longitudinal-connected foundation plates,CRTSⅡslab track sets type ∏ terminal restricted configuration anchorage structure in the bedroad-bridge transition section,in order to transmit forces such as temperature force and braking force from foundation plate to subgrade.
The terminal restricted configuration which is utilized as the anchorage structure to circumscribe longitudinal displacement of ballastless track was first proposed by Germany and used in engineering practice [1].
Whether it is a true reflection of engineering practices will be proven by further experiments and theoretical researches.

Researchers have unanimously arrived at the conclusion that fly ash in concrete can control the temperature increase of mass-concrete and can be extensively applied to tunnel engineering (Yang Jing, Feng Naiqian, 1999; Zhou Shizao, Chen Zhiyuan, 2008).
In addition, in underground works, marine environment and water-power engineering which demand strong durability, the amount of fly ash can be as much as 25% to 40% and it may restrain alkali-aggregate reaction in concrete.
Measurement of concrete strength This experiment was conducted at a laboratory of Faculty of Mechanics and Civil Engineering, Huazhong University of Technology, Hubei Province, China.
Role of Performance and Application Concrete with mineral admixtures can be applied to bulk mass concrete engineering, underground work, harbour , road and bridge as well as ordinary civil engineering, especially engineering of high requirements for long-term strength.

Strength and Swelling Properties of Solidified Dredged Materials Dongxing WANG1, 2, a, Rachid ZENTAR1, b, Nor Edine ABRIAK1, c 1Civil and Environmental Engineering Department, Ecole des Mines de Douai, 59508 Douai, France 2Geotechnical Research Institute, HoHai University, 210098 Nanjing, China adongxing.wang@mines-douai.fr, brachid.zentar@mines-douai.fr, cnor-edine.abriak@mines-douai.fr Keywords: Dredged materials, cement, strengths, swelling Abstract.
Based on the basal characterization of dredged sediments, a series of tests, such as compaction tests, compressive strength and tensile strength tests and swell tests, are performed to explore the engineering properties of treated materials.
For sediments mixed with cement, it is generally accepted that several reactions, such as pouzzolanic reaction, cation exchange reaction, flocculation and agglomeration, contribute to improve engineering properties of dredged sediments.

On the Investigation of Flow around the Square Cylinder Based on Different LES Models Zhe Liu1, a 1 Department of Civil Engineering, College of Engineering, Shantou University No.243 Daxue Road, Guangdong Province, P.R.CHINA, 515063 aliuzhe@stu.edu.cn Keywords: LES, WALE, LES-dynamic model, Abstract.
Although the conventional Reynolds-averaged Navier–Stokes (RANS) model has been widely applied in the industrial and engineering field, it is worthwhile to study whether these models are suitable to investigate the flow filed varying with the time.
