High Rock Fill Embankment Construction Technology And Quality Control

With the rapid development of the constructions in mountain areas, high-fill embankments, especially high-rock filled ones will be widely applied. Of all the questions during the construction of such embankments, such ones are needed first to be solved as finding economical construction ways and easy-to use quality control methods. In this paper, thoroughly discussed are Construction Technology and Quality Control of High-filled Embankment based on the joint research project, Research on Construction Technology and Quality Control of High-filled Embankment, by Guangxi Highway Management Bureau and College of Civil Engineering, Hunan University.In this paper, first discussed are the corresponding results in highway and dam constructions and the engineering characters of rock-fills are deeply analyzed, especially the relationships between gradation, strength and maximum dry density, long-term stability of fillers including earth-fillers and rock-fillers and some conclusions of use are drawn. By in-situ tests and researches on compacting mechanism of high-filled rock embankments, effecting factors on compaction, construction technology and shock compacting technology, obtained in this paper are the compacting technology of high-filled rock embankment and the optimal parameters of rolling compaction. By deeply research on the theory and methods of quality control of high-filled embankment, settled are the questions as quality detection method and control standard of high-filled rock embankment. Also settled in this paper is the question of how to observe the settlements of high-filled rock embankment. By analyzing the observation data of the ground and embankment settlements, a settlement predicting model is brought out in this paper, which can well predict the settlement. By deeply analyzing the effecting factors of slope stability, some conclusions of use are also drawn in this paper.
