摘要

本文采用数值方法研究了加筋土基础提高浅基础对土壤的承载压力的效益。土工格栅加筋土的数值研究涉及土工格栅性能的估计和验证。采用克里格法对加筋土基础进行了可靠性设计。它涉及使用任何确定性岩土数值模型生成的样本校准和验证克里格模型。代理模型简化了概率计算和蒙特卡罗模拟。该设计方法适用于多层土工格栅加筋的浅基础。结果表明，采用替代模型设计土工格栅加筋土基础具有减少沉降、提高承载力，从而减小地基面积的能力。

Reliability-based design of geogrid reinforced soil foundation using kriging surrogates

This paper investigates the benefits of using reinforced soil foundations to improve the bearing pressure of shallow foundations on soil using numerical methods. Numerical study of geogrid reinforced soil involves estimation and validation of geogrid properties. Reliability-based design of reinforced soil foundation is performed using kriging surrogates. It involves calibrating and validating a kriging model using samples generated by any deterministic geotechnical numerical model. Surrogate models simplify probabilistic computations and Monte Carlo Simulations. The design methodology is applied for a shallow foundation on soils reinforced with multiple geogrid layers. Results demonstrate the possibilities of surrogate modelling to design geogrid reinforced soil foundations and their capability to reduce settlement and improve bearing capacity, thereby reducing foundation area.
