英文摘要：

As viewed from the ideas of systematic geosciences, the inherent development courses of rock-soil numerical simulation are reviewed by a way combining geology with mechanics. Furthermore, a thoughtful exploration of methodological significance is presented. Four characteristics of the current researches on rock-soil numerical simulation can stand for the latest development of aforesaid research. The first feature is basic work of geological investigation outdoor. Then, various mathematical analysis approaches have been used to explore and understand the complicated phenomenon of geologic movements. The third is related to numerical simulation, which should reflect the integration of technological flexibility and geological system in both space and time, i. e., every interpretation and accounting for the truth of geologic movements are necessary to take the consideration of the adaptability of numerical methods and the actual requirements of engineering projects. Finally, the most effective ways and main direction to solve the current problems on rock-soil engineering are proposed to integrate reliability theory with mechanics numerical simulation technique.
