Abstract: The stability of roadbed along river smay be more vulnerable than that of other roadbeds, for it is easy to be influenced by hydrologic and weather change and becomes instable. It is very useful to investigate the factors affecting its stability.So it is very rewarding to strengthen the roadbed stability in practical engineering to find out themain factors and their ways affecting the stability of soil roadbed along the river.Based on the ideas of geology and mechanics,the influence of ground water on the stability of soil roadbed along rivers is analyzed.The cause and mechanical mechanism of surface water destroying the soil roadbed along rivers are explored.

Key words: soil roadbed, stability, ground water, surface water
