【 摘 要 】

Based on a high fill subgrade in Indonesia, this paper uses finite element software to simulate the settlement deformation characteristics of high fill subgrade under the condition of reinforced cushion. The calculation results show that although the existence of the reinforced cushion cannot significantly reduce the foundation settlement, it has obvious effect in ensuring the stability of the shoulder. The stability safety factor of the 9m high roadbed with the reinforced cushion layer increases by about 0.2. It is suggested that the reinforced soil cushion can be used as a reinforcement measure to ensure the stability of the shoulder when high-fill roadbed construction is carried out on soft soil foundation.
