触探试验——通常是指静力圆锥贯入试验或荷兰式静力触探——在荷兰、比利时以及其它各国应用日益广泛。在欧州大陆,它应用于各种工程地基勘察已有三十多年的历史。特别是在最近五年,由于在测试系统中有了新的发展,即电测探头,从而使这项试验特别可靠及有效。这种试验的成果,即探头阻力随深度变化曲线,用于地基设计时,可借助于经验方法,计算出桩基及浅基础的承载力及沉降值。
Penetration tests, usually referred to as static cone penetration tests or Dutch cone penetration tests, are increasingly used in the Netherlands, Belgium, and other countries. In continental Europe, it has been used in various engineering foundation surveys for more than 30 years. Especially in the last five years, due to the new development in the test system, namely the electric probe, the test is particularly reliable and effective. The results of this test, ie, the probe resistance change curve with depth, can be used to calculate the bearing capacity and settlement value of pile foundations and shallow foundations by means of empirical methods.
