At present, the most direct and extensive research method which in the field of engineering geology and rock soil mechanics is a numerical analysis method .But the numerical analysis method is developing from two-dimensional to three-dimensional . The slope stability not only has something to do with engineering geological condition , but also with the concave and convex extent of the slope. The text tries to present the three-dimensional effect of the slope by the three-dimensional model, and takes the example of Jilinguole 2 strip mine irregular three-dimensional slope, researching the three-dimensional model method of the irregular slope stability by AUTOCAD and ANSYS, founding the FLAC3D.This paper analyzes the stability of the Jilinguole 2 strip mine south slope by numerical simulation analysis.

Based on requirements of pipe transport systems on deepwater pipelaying vessel, a new pipe lifting mechanism was designed. It was composed of crank-rocker and rocker-slider mechanism with good lifting capacity and high efficiency. When the slider went to the upper limit position, the mechanism could approximatively dwell, meeting the requirement for transverse conveyor operation. According to the theory of dynamics, numerical analysis method was used to the dynamic analysis of the mechanism. The results showed the maximum counterforce was at the joint between the rocker and ground, and this calculation could be a guideline for the kinematic pair structure designing.
