【摘要】 在落锤式冲击荷载下，通过对饱和砂土砂面沉降量的测量，得到液化前和液化后又重新固结的饱和砂土相对密度的变化规律，以及相对密度增量与初始相对密度的关系。对不同落高下砂面沉降量的测量，得到冲击强度与沉降量的关系。这些结果可指导爆炸法密实砂土地基工程。更多还原

【Abstract】 The settlement of saturated sand in a cylinder induced by impact loading is measured. The changes of relative density and initial relative density are also deduced. The relationship between intensity of impact and settlement of sand surface is obtained by changing the drop-height of sand sample. The measured results are identical to related correlative reference and can be referred and generalized for application in engineering.更多还原
