Abstract Because of engineering geologic condition，hydrogeological condition and artificial factor，it is easy to result in landslide at tunnel face. Taking the Henglutou tunnel face engineering of the Hangzhou—Qiandaohu Expressway in Zhejiang Province as an example，firstly，the mechanism of landslide is analyzed in three aspects such as geological factor，water effect and human factor. Then，the landslide process and feedback monitoring data are dynamically analyzed；and the effect of construction measures is checked up. Finally，the process of landslide is simulated by FEM of Plaxis. Through effective monitoring dynamic feedback，the slope at tunnel face can be controlled；and landslide can be forecasted. The construction risk of tunnel face could be reduced greatly and construction safety of tunnel face could be assured.
