Abstract: High-enrockment embankment chronically received the effect of dynamical load in the run course after the construction. Based on the resemble scale theory, a dynamical response indoor model of high-enrockment embankment are used to simulate the syntony load and impact load is established. The factual complicated dynamical load of high-enrockment embankment received. Using dynamic earth-manometer and accelerometer to pick up response wave; Using Drucker-Prager elastoplastic model to analyze dynamical response finite element on high-enrockment embankment. It was shown that the finite element analytical result was in good agreement with experimental data; even under the bigger dynamical load, plastic area in high-enrockment embankment was also just temporary and partial; it still could maintain whole stability, and expressed a dynamical strain hardening characteristic.

Key words: high-enrockment embankment, dynamical response, indoor model experiment, elastoplastic model, finite element analysis
