Abstract: The construction of highways, airports and earth-rock dams in hilly and gully areas often occurs with high fill engineering.The post-construction settlement is difficult to calculate, predict and control in high fill engineering.This paper systematically investigates the existing high-fill engineering cases and research literature, and summarizes the post-construction settlement control standards for high fill engineering, analyzes the influence of the two main control factors of fill height and soil type on the post-construction settlement law, and finds there are big difference about the post-construction settlement mechanism and law of coarse-grained soil and fine-grained soil.Based on the high fill engineering of two different types of soil, the mechanism and inducement of post-construction settlement are briefly explained, the difference between the two post-construction settlement deformation laws and the main controlling factors are analyzed, and the calculation theory model of fine-grained soil is summarized.Including estimated empirical model with coarse-grained soil, as well as other commonly used post-construction settlement prediction models for high fill engineering.The post-construction settlement prevention measures commonly used in current projects are listed from three aspects:improving the bearing capacity of the original soft soil foundation, enhancing the strength of the filler itself, and adding prevention and drainage measures.The research conclusions of this paper can provide reference for post-construction settlement prediction and control measures of high fill engineering.
