前言 触探试验(包括静力触探与动力触探),是将一根带探头的金属杆压入或打入地下,用以测定地下土层的贯入阻力,然后,根据贯入阻力来确定地基土的承载力等指标。早在19世纪末期,瑞典的铁路部们在工程地质勘察中就开始采用触探试验,美国使用标准贯入试验,也有40多年的历史,30年代初期荷兰首先采用现代静力触探试验。近十年来,由于测试技术有了新的发展,这种简便、准确和经济的测试方法在国际上得到了
Introduction The penetration test (consisting of static probing and dynamic probing) consists of pushing a metal rod with a probe into or out of the ground to measure the penetration resistance of the subterranean formation, and then, based on the penetration resistance. Determine the bearing capacity of the foundation soil and other indicators. As early as the end of the 19th century, the Swedish Ministry of Railways began using the penetration test in the engineering geological survey. The United States used the standard penetration test and also had a history of more than 40 years. In the early 1930s, the Netherlands first used the modern static penetration test. In the past decade, thanks to new developments in test technology, this simple, accurate and economical test method has been internationally
