Abstract Research purposes：The design of slope rock-soil engineering has to be made on the basis of the analysis with the different parameters and models for the rock and soil because of the complicated geological condition and limitation of the geological survey, but the choice of model for rock and soil and mechanics analysis are rather complicated. Especially for the area with complicated geological condition, the calculation and analysis are more difficult, resulting in many uncertain factors. What presented in this paper are the countermeasures for reducing the influence of uncertainty of slope rock-soil engineering.
Research conclusions：The dynamic design and dynamic construction method have bright applicable future in the slope rock-soil engineering. Whether the design of rock-soil engineering is reasonable or not relates to the adaptability of the engineering measures to the geological conditions. In course of the construction, the information collection system should be established, and the designed mechanics model for rock and soil and relative parameters must be modified and improved according to the geological conditions revealed by excavation and other engineering. In this way, the actual dynamic design and construction can be realized to make the design and construction more adaptable to the features of the slope rock-soil engineering with more safety and higher efficiency. So the dynamic design and construction are the effective way for reducing the uncertainty of the slope rock-soil engineering.
