Pavement deformation - Guangzhou Dongfeng Road project

In the Dongfeng Road project, our company undertook the monitoring of pavement deformation. In order to ensure the settlement control effect after construction, the settlement deformation of the subgrade (including the foundation and the body) should be continuously monitored during and after the filling. In the process of embankment filling, guide and control the filling rate, conduct comprehensive analysis according to the settlement observation data observed for several months under stable load conditions, timely adjust the design to make the foundation treatment meet the predetermined deformation control requirements, and determine the construction time of track structure and carry out the construction of track structure when the settlement is stable and the post-construction settlement meets the requirements. At the same time, guide the adjustment of track parameters, maintenance and maintenance during operation to ensure high-speed, smooth, safe and comfortable operation of the train.
