摘要
对碎石土用强夯法进行加固的室内模型试验,整理分析其试验资料,得出了土体的变形特征,从中归纳出粗粒无粘性土的强夯机理,并考虑能量和夯击次数两因素的影响,给出了有效加固深度的经验计算公式。
This paper investigates the regularities of gravel deformation, analysing the results of several model tests of gravel by dynamic compaction. As a result, the compaction mechanism of coarse non-cohesive soil is obtained. Finally, an empirical formula for effective strengthening depth is derived from both compaction energy and blow number by using mathematical statistics.
