| The engineering of bridge foundation in deep water combine the process of design with construction. The foundation under water will be acted by the surrounding water it can bring out some problems to the technology of design and construction. So all the problems such as drilling method,foundation types,depth of foundation,load reaction and relationship of foundation bear force and its sedimentation are all connected with the water. This article is based on the engineering of Huluding bridge in Nanning provinces, and take the foundation of deep water as research object, introduced the whole process of the engineering ,from perambulation,design to construction. according to the material situation and use the experiences of relative engineering for reference, studied the design parameter,equipment choice and construction techniques in detail., the contents are as follows:1) Based on the analysis of the relative information and the fact of the engineering selected the foundation type to bring the gist to the design and construction of bridge deep-water foundation.2) Discussed the process of project comparison and based on the selected project to analysis the method of parameter choice and calculation, it can provide the basic data to the construction process.3)Aim at the characteristics of the construction of under-water, detaily analyzed the construction techniques and construction process of bridge deep-water foundation, from construction preparation,construction process and construction quality check-up .4) Take the typical pier foundation as an example, analyzed the process of quality check-up and quality control of deep-water pile foundation, analyzed the quality defects of construction according to the check result, it provides the reference to find the quality control point and constitute the quality control measure.Whereas the own characteristics of Huluding bridge :large span and large width, its span is the first in Guangxi province and it is also at the top of the similar bridges in China. The construction of this bridge is help to promote the development of bridge engineering in our country, it is significant to the theory and reality to study the process of design and construction, so the results of this article can be acted as a reference to the... |
