Abstract The robust geotechnical design (RGD), which aims to ensure a design that is robust against variations in the input variables, is receiving wider attention and acceptance in the past few years. In this paper, the authors proposed the sensitivity of reliability index (SRI) to evaluate the feasibility robustness of the design, resulting in a modified RGD approach. The performance of the proposed approach was examined by a geotechnical design example, and its advantages are evidenced.

基于可靠性指标敏感性的改进稳健岩土设计方法

摘要 稳健岩土设计（RGD）旨在确保设计对输入变量的变化具有稳健性，在过去几年中受到了更广泛的关注和接受。在本文中，作者提出了可靠性指数 (SRI) 的敏感性来评估设计的可行性稳健性，从而产生了一种改进的 RGD 方法。通过岩土工程设计实例检验了所提出方法的性能，并证明了其优点。
