粉土地基承载力标准值计算经验公式的探讨

Approach to the empirical formula of the basic bearing capacity in the silt foundation

确定地基承载力是地基设计的重要问题 ,在规范法确定地基承载力基本值时常遇到实际指标与规范指标不相符、使用内插法又不方便的情况 ,通过对粉土地基承载力基本值与其主要影响因素的关系进行分析 ,提出确定该类地基土承载力基本值的经验公式 ,简便合理 .

The interpolation method in deciding the bearing capacity of the silt foundation which was recommended by the norm usually has some realistic difficulties, This paper presents the empirical formula through studying the influencing factors. It is shown that the formula is convenient and effective in silt foundation designing.
