Study on Settlement of High Fill Embankments on Rock Slope under Complicated Stress Conditions

Abstract

Compared with general roadbed，high fill embankment has the characteristics such as higher height， larger cumulate settlement and it’s stability should be technical analyzed. High fill embankment is one of the most important projects in highway engineering. The settlement in highway construction, especially the differential settlements, may lead to the cleft and stagger of pavement，and largely affect the quality of driving as well as the operational life span. So how to reduce the settlement and get rid of the danger made by the settlement has been an important subject in highway construction field and the research has important reality significance. Therefore, in order to master the deformation law of high fill embankment on rock slope under complicated stress conditions, systems of monitoring network are established to monitor the settlement of high embankment with strong weathering filling, high embankment on rock slop and high rock fill abrupt slope embankment respectively. Through analysis of settlement of high fill embankment stability under complicated stress conditions, conclusions are made in details.
