| 摘 要： | 作为一类重要的基坑支护结构,重力式挡土墙整体稳定性研究一直备受众多学者极大的关注。从可靠度的几何意义出发,通过MATLAB编写程序,对最危险滑弧面所对应圆心进行全域搜索,并利用梯度优化法计算整体稳定可靠度,提高了整体稳定可靠度的计算精度。同时,计算了其模糊可靠度,对比计算结果可知,模糊可靠度理论能更加科学、全面、客观地反映复杂的岩土工程可靠度问题的实质。

| Abstract: | As a kind of important foundation pit supporting structure, the gravity retaining wall has always drawn many scholars' attention. Aiming to start with the aspect of the geometric meaning of reliability, we can use the global searching method of the most dangerous sliding surface corresponding to the center of the circle through MATLAB programming, and use the gradient optimization method to calculate the overall stability reliability. Finally, the accuracy of the overall stability is improved. The results of comparison can be known that fuzzy reliability theory can be more scientific, comprehensive and objective to reflect the essence of complex geotechnical engineering reliability problem. |
