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.

The successive stability constants which are obtained by non-linear least-squares methord fitting Bjerrum formula. In three- system ,the results from Scatchard plots indicate that there exists two strong binding site of Mn and one strong binding site of Zn,there are same results compareing with two -system ,but some more weak binding sites are different from the different addition sequence ,show that there are not common strong binding site of Mn,Zn in HSA or BSA .Strong binding sites have electiveness and unfalteringness ,weak binding sites exists irreversibility.

用非线性最小二乘法拟合Bjerrum方程，计算了同时竞争体系的逐级稳定常数；Scatchard图分析表明，三元体系中，Mn和Zn与血清白蛋白结强合部位数分别为2和1，与二元体系相比，保持不变，弱结合部位数随加入顺序的不同而不同，但都有所增加，竞争结果说明了Mn和Zn与血清白蛋白结合没有共同的强结合部位，强结合部位具有专一性，选择性，而弱结合部位具有不可逆性。
