To analyze the settlement characteristics of semi-separated embankments on soft soil foundation, based on the actual project and combined with the field test results, a numerical model was established to study the settlement characteristics of semi-separated embankments and analyze the influence of different engineering factors on settlement characteristics. The results indicate that the settlement shape of the semi-isolated embankment's top surface is an asymmetric "bowl-shaped" curve, with the maximum settlement point offset towards the edge of the embankment, and the differential settlement value after construction is smaller than that of the integral embankment. the width and height of the partition as well as the pavement load are the main factors affecting the settlement pattern of the semi-separated embankment. The geogrid modulus has an obvious influence on the position of the maximum settlement point after construction, and reasonable pile spacing plays an important role in the settlement stability of high embankment roadbases.
