Testing and Control for Strands Embedded in Annular Concrete Foundation Beam of Steel Archaize Tower Xiaoke Li a, Jian Liu b, Zhihao Wang c and Pengfei Han d North China University of Water Resources and Electric Power, Zhengzhou 450011, China alixk@ncwu.edu.cn, b59993455@163.com, cwangzhihao916@126.com, d531834812@qq.com Keywords: pre-stressed concrete; annular anchor; friction coefficient; circumferential stress; field test.
Introduction Annular anchor is a special anchor system for prestressed concrete structures used in water conservancy project, municipal engineering, silo, gas and oil storage tanks, reactor containment, and so on.
More than that, the actual effects of prestressing steel reinforcement could be tested by embedded professional sensors in the structure.

As a professional analysis tool, it is specifically developed for geotechnical engineering, with powerful functions, a friendly interface for users.
Its step-by-step construction mode can be given by activating or frozen soil type groups, structures, loads or changing the water level, to achieve the real simulation of construction and the excavation process.
The sheet pile is precast reinforced concrete pile , its thickness is 400mm; The anchorage structure is a cast-in-situ concrete anchorage wall , its average thickness is 650mm ;bars with a diameter 55mm are made of Q235 steel, spacing 1.5 m; through the construction process, uniformly distributed load on wharf surface is 10Kpa; the construction method is first driving the sheet pile with last digging basin;the calculated water level has considered the most unfavorable condition, taking the design low water level.
