Research on Mathematical Model of Flow and Sediment Erosion Evolution at Wassit Power Station in Iraq Mingjin Zhang1, 2, a and Huaqing Zhang2, b and Hongqian Zhang3, c 1School of Civil Engineering, Tianjin University, Tianjin, 300072, China 2 Tianjin Research Institute for Water Transport Engineering, Tianjin, 300456, China 3Hohai University, Nanjing, 210098, China azhang_mingjin@vip.sina.com Keywords: Numerical simulation, Flow, sediment erosion, Intake.
The calculation results based on the data of flow and sediment in representative year show that the erosion and deposition will occur in the region of water intake engineering.
Foundation schemes of the water intake engineering is designed with one intake pump barge, two pressure delivery pipes which are laid out on the steel trusses and approach bridge.

Continuous bridges jolted the public attention into the awareness of the seismic vulnerability due to its wide application in bridge engineering.
It is therefore of great engineering significance to improve their seismic performance.
Engineering Situation and Modeling Fig. 1 The layout of the bridge The Yellow River Bridge is an important bridge across the yellow river, which is located at Western development inter-province highway of the Inner Mongolia Autonomous Region.

Evaluation of Shrinkage Resulted Cracking of High Strength Calcium Sulfoaluminate Cement Concrete with Impact of Internal Curing LUOSUN Yiming, ZHANN Jun, GAO Yuan Key Laboratory of Safty and Durability of Civil Engineering of China Education Ministry, Department of Civil Engineering, Tsinghua University, Beijing, 100084, China E-mail: lsym1230@163.com, junz@tsinghua.edu.cn, y-gao04@mails.tsinghua.edu.cn Key words: high-strength concrete; calcium sulfoaluminate cement; shrinkage; ring test; cracking; internal curing Abstract: In this paper, restrained ring test and shrinkage test are carried on three kinds of concrete—high-strength portland cement concrete, high-strength calcium sulfoaluminate cement concrete and high-strength calcium sulfoaluminate cement concrete with internal curing in order to evaluate the shrinkage induced cracking performance of the concretes.
Introduction In recent ten to twenty years, large amount of existing buildings and civil infrastructures built in the last century are gradually started to be strengthened or retrofitted in order to fulfill the safety and new demands.
In order to attain the required performance, such as strength within a period as short as possible, concretes with both high strength and rapid hardening characteristics are of great interest to engineers [1].

Research and Benefit Analysis on Exterior Mesh Construction Technology of Super Cross-section CFST Cylinder Chuanqin Yao 1,Xue Bai1, Rong Bai2, Chao Wang1, Haibing Ma1 1School of Civil Construction, Anhui University of Science and Technology, Huainan, Anhui, 232001 2China Construction Fourth Engineering Bureau, Guangzhou, 510665 76331022@qq.com Keywords: Super cross-section, CFST, construction technology, benefit analysis Abstract.
During the development process, the fifth structure type, new composite structure of concrete-filled steel tube, becomes more and more popular in design and construction and also among the engineering technical personnel.
Civil engineering and steel structure need to complement each other in construction, to ensure the successful completion of the detection of steel structure, the welding of fastening nails and the mesh work before plastering.
Preparation before construction. (1) Team preparation: the manual plastering protective layer construction of exterior mesh for high-rise CFST super cross-section cylinder involves the cross operation of various types of work, such as civil construction team, steel structure construction team, third-party testing department of steel structure, frame climbing profession and so on, therefore, the requirements for the communication and coordination between various types of work is relatively higher, several teams are required to work simultaneously
