INTRODUCTION For a long time, designers and builders aim at the problem of pile foundation considering mainly intensity far as the durability of the structure strength.Over the past 20 years, The survey data of these countries who have more coastal engineering and more advanced technology like the United States, Britain, the Netherlands and Japan indicates that buildings of pile foundation in the splash zone,mostly use less than 20 years, have to cost a huge sum of money to repair because of the serious of reinforcement corrosion and concrete crack.In recent years, although the scientific research workers have made great efforts in our country,But for some new pile wharf,including the large prestressed concrete pipe pile wharf building in the early 90 s, According to the survey,under a variety of comprehensive factors the concrete component surface have micro cracks and mild rusty spot Because of the bad environment Building after five years in Southern port.And 7 ~ 15 years or so, Artifacts
The durability of the Pile foundation concrete depends on the degree of protective measures of reinforced concrete.In this paper,The author analyzed the Research of Ring pressure of the Pile foundation on the influence of the durability of concrete by Simulation of the actual engineering environment and measuring the concrete of Pile foundation corrosion mass loss before and after freezing and thawing in three kinds of solution.
Because exposure on both ends of steel tube outsourcing concrete in the experiment,And all soaked in the solution,Solution enter into the concrete easily along the ends and the inner wall ,So the mass of concrete peak approximation after freeze-thaw 100 ,At this point that internal concrete is in the saturation stage,Then the mass change gently,Even fall.While outside spray coating exposed at one end,Solution penetrate slower than steel tube outsourcing concrete with multiple function,So the mass change curve smooth and no obvious peak in the 300 freezing and thawing and In 300 freezing and thawing concrete failed to reach saturation.But in the practical engineering and the actual environment, steel tube outsourcing is above the liquid level,Concrete is not contact with solution,So in the actual number of freezing and thawing in analogy to the laboratory after reaching 300 times,The practical engineering is not saturated ,So laboratory life prediction is less than the equivalent conditions

A Comparative Research on Thermal Stresses Calculated from Different Element Models of a Concrete Continuous Box-Girder Bridge Feng Xu1,a, Bo Wang 2,b, Hailong Zhang3,c 1,2,3 School of Civil Engineering & Mechanics, Huazhong University of Science & Technology,Wuhan 430074 CHINA a xufeng1979917@163.com, bwangbohust@126.com, czhhlhust@163.com Keywords: concrete continuous box-girder, gradient temperature load, thermal stress, beam element, solid element.
Introduction Many previous experimental/theoretical researches (e.g.[1,2]) and engineering accidents indicated that the temperature effect upon bridge structures may be notable, in some circumstances, even much more prominent than that caused by live loads.
Bridge engineers have given more and more weight to temperature effect, as an outcome of which the gradient temperature distribution along vertical direction in cross section that specified in China's code (JTG D60-2004) was redefined referring to the specifications of AASHTO[3,4].
Calculated from the beam model, total thermal stress results at top of the deck centre in the middle cross section of the mid-span closure segment is -8.08MPa, while the result from the solid model is -8.74MPa (See Figure 8(a)), which is close enough to -8.08MPa in engineering issue.
