The PRD is widely distributed with deep soft soil subgrades,and its post-construction settlement is one of the main factors af-fecting the stability and safety of roads during operation.In order to better study the settlement trend of deep soft soil subgrade,this paper relies on engineering examples,adopts four prediction methods to fit settlement monitoring data,and evaluates and compares the accuracy of these methods based on measured data,so as to predict post-construction settlement.The prediction results show that for the deep soft soil subgrade treated by plastic drainage board and cement mixing pile,the most accurate settlement prediction method is the hyperbolic meth-od.The settlement amount of soft foundation after plate and pile treatment can meet the requirements of the specification,which proves that the treatment plan is reasonable and effective.
