From the basic concepts and principles of systems engineering, the course system related to the slope ecological protection engineering is analayzed, which is a typical systems engineering. Talking the rock slope ecological protection engineering at Guizhou Guangzhao Hydropower Station for example, the application of systems engineering in the slope ecological protection engineering is researched. Using the technology of vegetation-growing concrete, the plan of protection and revegetation for this slope is turned out. It shows that systems engineering has a good applicability to slope ecological protection engineering.

Jointed Rock Slope

In order to study the failure mechanism and assess the stability of the inlet slope of the outlet structure of Lianghekou Hydropower station, the strength reduction method considering the ubiquitous joint model is proposed. Firstly, two-dimension numerical models are built to investigate the influence of the dilation angle of ubiquitous joints, mesh discretization, and solution domain size on the slope stability. It is found that the factor of safety is insensitive to the dilation angle of ubiquitous joints and the solution domain size but sensitive to the mesh discretization when the number of elements less than a certain threshold. Then, a complex three-dimension numerical model is built to assess the stability of the inlet slope of the outlet structure of Lianghekou Hydropower station. During the strength reduction procedure, the progressive failure process and the final failure surface of the slope are obtained. Furthermore, the comparison of factors of safety obtained from strength reduction method and analytical solutions indicates that the effect of vertical side boundaries plays an important role in the stability of jointed rock slope, and the cohesive force is the main contribution to the resistant force of vertical side boundaries.
