中美标准贯入试验的差异研究及应用

标准贯入试验（SPT）作为原位测试试验，通过标贯值及修正评价岩土物理力学参数。工程原位测试证实，美国标准与中国标准贯入试验存在不少差异，对比两者标贯测试的原理、方法、过程、数据及能源效率的选取，分析中美标准贯入试验的差异及应用。

Study on the Differences and Application of SPT between China and America

Standard penetration test as the in situ testing, evaluates the physical and mechanical parameters of rock and soil by standard penetration value and correction. The test proves that there are many differences between the American standard and the Chinese standard in the penetration test. By comparing the principle, method, process, data and energy efficiency of the two standard tests, the difference and application of the standard penetration test between China and the United States are analyzed.
