Through the research of direct search method based on 3D FEM, and its application for the tunnel slope stability analysis, the objectives of this work in this paper are as follows:1. The dynamic programming as well as its application for 3D side slope stability analysis is studied. With the introduction of graph theory concept, one kind of glide pattern of 3D slope is constructed, and the critical slip surface with smallest safety factor is searched with the aid of one auxiliary function including safety factor;2. Using the C++ programming language, the 3D slope stability analysis and the direct search procedure is established, and this method is testified applicably by some contrast analysis, also some influence factor in analysis is discussed;3. Integrated with the different actual situation in tunnel slope, considered its excavation, timbering and rain infiltration, its stability influence and rule is researched used this method, also some processing measure is proposed.

Controls were matched the study cases by gender, age and location of residence. Results The scores for mature coping strategies and for social support measures were significantly lower in attempter than in non-attempters. In contrast, the scores on the less mature coping strategy scales were significantly higher in attempter than in non-attempters. The scores for mature coping strategies and social support were still much lower in 73 attempters without a mental illness than in their matched controls.
