在量纲分析的基础上,利用尺寸为100cm×100cm×80cm的模型试验坑,采用落雨法充填粗砂土,对之施加四种不同能量的冲击能,测量产生的夯坑深度,建立了无量纲夯坑深度与土质参数和施工工艺参数无量纲量间的相关方程,用工程实例对建立的方程进行了验证。结果表明,方程可用于推算现场强夯时的夯坑深度,并由此可进而据此推算场地平均夯沉量。 On the basis of dimensional analysis, using the model test pit with the size of 100cm × 100cm × 80cm, filling the coarse sand with the falling rain method, applying four kinds of impact energies with different energy to measure the tampered pit depth, and establishing The correlation equation between dimensionless rampen depth and soilless parameters and construction process parameters is established, and the established equation is validated by engineering example. The results show that the equation can be used to calculate the tampered pit depth during the dynamic compaction of the site, and thus the average settlement of the site can be calculated accordingly.
