In order to simplize analysis, physical mechanics parameters of geotechnical materials are chosen as random variables in this paper, and others are temporarily dealt as definite values.
In order to make it easy to understand, all kinds of geotechnical materials properties can still be thought about as random variables which have no connections with time.
Thus it can be seen, the ignorance of the uncertainty of geotechnical material’s parameters will make a big impact on the computed results of the reliability of landslide, it’s inadvisable and dangerous.
Landslide stability analysis methods are various, which have their advantages and limitations respectively, we should utilize a variety of analysis methods synthetically, based on the principle of system science, using comprehensive integration method, make full use of the existing engineering experience and a variety of theories and methods to make quantitative and qualitative analysis.
