In this paper, we aim to promote the capability of solving two complicated nonlinear differential equations: 1) Static analysis of the structure with variable cross section areas and materials with slope-deflection method; 2) the problem of one dimensional heat transfer with a logarithmic various surface A(x) and a logarithmic various heat generation G(x) with a simple and innovative approach entitled “Akbari-Ganji’s method” (AGM). Comparisons are made between AGM and numerical method, the results of which reveal that this method is very effective and simple and can be applied for other nonlinear problems. It is significant that there are some valuable advantages in this method and also most of the differential equations sets can be answered in this manner while in other methods there is no guarantee to obtain the good results up to now. Brief excellences of this method compared to other approaches are as follows: 1) Differential equations can be solved directly by this method; 2) without any dimensionless procedure, equation(s) can be solved; 3) it is not necessary to convert variables into new ones. According to the aforementioned assertions which are proved in this case study, the process of solving nonlinear equation(s) is very easy and convenient in comparison to other methods.

依据土体应力状态、计算边坡稳定安全系数的思想,结合对土体根本性质的认识,对基本假定、公式推导过程和工程应用进行了详细的说明。由于土坡稳定安全系数的计算公式在理论分析依据是严密的,推证得到的计算公式是正确的,所以在工程实用是可靠的。文章为该方法的工程应用和深入开展相关的研究奠定坚实的基础。

将最大熵原理应用于基本复合形法的优化计算中,旨在提高算法的寻优成功率。具体步骤为:选取复形中熵最大的顶点为寻优点;在复形其余各点的加权中心点与寻优点的连线上,搜索比寻优点改善的新顶点;并替换掉寻优点构成新的复形;如此迭代直至复形中的信息被完全利用。采用基本复合形法和基于最大熵原理的复合形法对两个复杂土坡的最小安全系数进行了搜索,结果表明基于最大熵原理的复合形法的全局搜索能力有了明显改善。
