软土地基桥台现场试验监测方法与技术研究

快速铁路对于线下结构变形和刚度的控制十分严格,特别在高填土深层软土地区修建桥台,为了使桥台基础系统的变形处于可控状态,进行现场试验监测十分重要。介绍了对务山特大桥温州桥台施工阶段现场试验监测系统的目标、构建原则,重点阐述了该试验监测系统的布置方法和测试技术,这些都在现场得到了成功实施。

Study on Technology and Methods of Testing and Monitoring the Abutment on the Soft Ground

The high-speed railways request strict control of infrastructure's deformation and stiffness,especially in the construction of abutment in the deep soft soil areas with a high earth fill.To control the abutment's deformation effectively, it is very important to carry on testing and monitoring on site.This paper introduces the aims and construction principles of the testing and monitoring system in Duiwushan Great Bridge's Wenzhou Abutment,and explains in detail the system'op- erational disposal and testing technology,which have been successfully put into practice on site.
