碎石土地基极限承载力统计分析

Statistic Analysis of the Ultimate Bearing Capacity of Foundation Ground on Gravelly Soils

根据收集的地基荷载试验资料和在前期工作的基础上，运用概率统计原理和工程经验，提出了碎石土地基极限承载力标准值表及其分布类型和统计特征参数。为《桥规》修改和按地基基础可靠性设计奠定了基础。

Based on the collected test data about foundation load and the work done in earlier stage, the nominal value form of the foundation ultimate bearing capacity on gravelly soils, the distribution type and the statistic characteristc coefficients are obtained by using the principle of probabilitistic statistics and engineering experience. This lays a foundation for revise of The code for design on subsoil and foundation of railway bridge and culvert and for the reliability design of subsoil and foundation.
