Zhongli landslide is located at the right side of Yanji-Tumen expressway. The mountain ridge was cut off during the process of road bed excavation. This causes the landslide. The determination of the shear strength of the slipped zone directly affect the results of stability evaluation and treatment design in the estimating of slope stability and the calculating of the landslide thrust. So it play an important role in the cost of this landslide treatment project. According to the fact that Zhongli landslide was sliding, and the importance of the determination of shear strength c、φ values of the slipped zone soil, by the method of anti-analysis,this paper gives more actually comprehensive shear strength indexes c、φ values which provide reliable basis for further calculation, evaluation and treatment.
