摘要
研究了岩石地基上扩展基础的破坏模式和承载性能,现场试验和数值模拟分析表明,岩石地基上扩展基础破坏模式为明显的受弯破坏,基底反力分布非线性特征较强,基底反力分布呈现中间大、两边小、边缘又有点增大的趋势。
Researches on the destruction pattern and the loading performance of the spread foundation on the rock foundation. By the analysis of the field test and numerical analysis, the destruction pattern of spread foundation on rock foundation is a obvious bending failure, nonlinearly distribution of pressure beneath foundation is more strong, the pressure beneath foundation shows a tendency by middle big, small nearby two and a little increasing in edge.
