摘要

采用试验程序和数值计算方法，研究了边坡对偏心加载条形基础承载力的影响。考虑了土工格栅加筋和未加筋砂坡两种情况。在不同偏心荷载作用下，对按比例调整的基础模型进行了试验。通过参数化研究，考察了不同偏心荷载作用下边坡对土工格栅承载力和层深的影响。结果表明，施加荷载的偏心距相对于边坡面的位置对承载力有显著影响。当从施加偏心荷载到坡面的距离增加时，后者也会增加。所得结果还表明，与水平地基预测结果相比，条形基础的承载力还取决于地表倾角。

Experimental and Numerical Investigation of an Eccentrically Loaded Strip Footing on Reinforced Sand Slope

An experimental program and numerical computations were performed to investigate the slope effect on the bearing capacity of an eccentrically loaded strip footing. Two cases were considered: unreinforced sand slope and reinforced slope by geogrid. Tests were conducted on scaled footing models under various eccentric loads. A parametric study was carried out to examine the effect of the slope on the bearing capacity and the depth of geogrid layers under different eccentric loads. It was shown that the location of the eccentricity of applied load with respect to the slope face has a significant effect on the bearing capacity. This latter increase when the distance from applied eccentric load to the slope face also increases. Obtained results also showed that the bearing capacity of strip footing also depends on the inclination of ground surface in comparison to that predicted from horizontal ground.

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
