世界各地标准贯入试验比较和共同问题

Current Status and Common Issues in Standard Penetration Tests for Soil Classifications around the World

标准贯入试验是国内外广泛使用的原位测试技术之一。本文在简单介绍该试验发展过程的基础上,对比了世界各地所采用的规范标准和应用的异同,深入地探讨了试验的测量手段、结果分析方法及能量传递等问题,指出了标准贯入试验的试验深度测量、能量传递测量分析、锤击数与贯入深度测量、N值定义及度量方法、贯入深度与N值及经验公式异地应用等一些共同存在的问题,提出了基于现代科学技术的解决途径和方法。

The standard penetration test is a widely used in-situ test method for soil classification in the world. This paper presents a brief review on the development history of the test and compares in detail the similarities and differences among the test standards and their applications in different regions and countries. The paper further examines the equipments, data analysis methods and energy transmission of the tests, On the basis of the examinations, the paper summarizes the common issues in the standardized test methods and points out the possible approach and methods to solve the common issues by using modern high technologies.
