摘要
首先进行了垂直静极限承载力实验,为确定垂直动载荷幅值的选择提供参考。然后重点针对载荷幅值和频率的影响进行了系列的室内小模型实验,并对结果进行了分析,获得了垂直动载下桶形基础在钙质砂地基中的响应特点。
Experiments to determine the vertical static bearing capacity are carried out a reference choosing of the dynamic load amplitudes. Then a series of experiments are made in laboratory to study the influences of the load amplitudes and frequencies. After we analyze the results,the respondent characteristics of bucket foundations in calcareous sand under vertical load are obtained.
