机会约束规划在岩土工程中的应用

采用极限平衡理论分析土坡稳定性, 搜索确定其潜在的滑动面与确立可靠度分析模型是理论研究与应用的两个重要方面。应用“确定的”方法, 构筑由随机变量决定的约束条件, 根据机会约束规模理论, 分析土坡的稳定性与可靠性。并用土坡实例进行计算。

APPLICATION OF CHANCE CONSTRAINED PROGRAMMING TO GEOTECHNICAL ENGINEERING

So far as staiblity analysis of slope, both searching and determing the potential sliding surface and creating model of reliability analysis are two important aspects in theoretical research and application from limit equilibrium theory. In this paper, according to the conventional calculation formula for slope stability analysis, the constrained condition determined by random variable is proposed for the stability and reliability analysis of soil slope by using chance constrained programming. Finnaly, a real case as an example is taken to calcualte the minimum safety coefficient and reliability index.
