Research on the measures to improve the durability of urban concrete bridges in Hebei province Shouqin Zhu a, Quanchao Bi b ,Honghuan Cui c Hebei Institute of Architecture and Civil Engineering, Zhangjiakou City Hebei province, P.R.China afeifan928@sina.com, bbenlad@sina.com, czhanliqun@126.com Keywords: concrete bridges; reinforced protection; crack control Abstract.
Introduction Our country has already faced the great pressure that engineering that has been built fails untimely .
Resistance to water penetration can be improved in the following aspects : a) We should designe and control the concrete mix ratio carefully and strictly, general requirements is controlling minimum and maximum amount of cement; The water／cement ratio should be required differently and controled strictly according to the different engineering object; appropriately raise the rate of sand to ensure the concrete workability and compactness; b) Require the gravel material strength, particle size distribution, cleanness strictly, in particular the mud content, is not allowed to exceed the standard limit absolutely; c) Through the experiment we chose proper admixture and mineral admixture, improve the durability of concrete,and improve the workability of concrete; d) Use mechanical agitation and mechanical vibration, especially in the reinforced -dense area, work should be done more carefully to ensure the compactness of concrete.

in-situ Measurement of Ground Vibration Induced by Inter-city Express Train Quanmin LIUa, Xun ZHANG, Zhijun ZHANG, Xiaozhen LI School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031, China aemail: qmlau007@126.com Keywords: express train; viaduct; environmental vibration; field measurement; vibration level Abstract: On the basis of the measured ground borne vibration of some inter-city express railway viaduct, test results analysis shows that: the test environmental vibration is under the limit set by standard of environmental vibration in urban area; whether transverse or vertical vibration, a rapid attenuation of the peak acceleration with the distance to the up-track center is observed, however the vibration at 7.5m appears to be amplified; the ground vibration with the distance conforms to a logarithmic relationship; the horizontal ground vibration at 7.5m caused by the elevated rail transit is larger 3.6cm/s2 than the vertical vibration; low-frequency vibration
In order to avoid the interference to ground vibration caused by other factors such as cars and engineering construction so on, the selected test site located in the open free field (Figure 1).

Introduction We often see the slide disasters that caused by the natural slope and the slope of formation in large-scale civil engineering.
Finally, it proves that the system can be used to quasi-real-time remote monitoring by field experiment and it has scalability and value of engineering applications based on its modular design.

Because the terrorist attacks are more frequent, the dynamic loading on the buildings of the explosion of modern explosives are larger than the initial designed load, and the explosive load is of so short time and great damage that people can hardly survive, the improvement of the antiknock performance of the important buildings has been the inevitable design problem in structural engineer’s consideration.
So it is necessary to do research into the explosion influence and damage to the civil architectures, to adopt reasonable design method for the antiknock design of the buildings and adopt feasible method to improve the antiknock performance of the existing buildings.
