摘　　要：静力触探作为一种轻便、快速、高效的原位测试技术,在岩土工程勘察、监测、检测等方面得到了广泛应用。国内静力触探主要为单桥静力触探,近年来双桥静力触探开始推广使用,但单桥静力触探与双桥静力触探之间关系的研究相对较少。本文简单介绍了单桥静力触探和双桥静力触探的优缺点,说明了建立两者之间关系的必要性。通过两项工程的对比试验研究,收集了大量试验数据,运用统计分析方法,给出了单桥静力触探与双桥静力触探之间的经验公式,并对其适用性进行了探讨。As a portable-fast-high in situ testing technology, cone penetration test has been widely used in investigation, monitoring or detection of civil engineering project. Cone penetration test is mainly single bridge probe in our country, and double bridge is being used rapidly recently. However, the study of the relationship between single bridge probe and double bridge probe is not so much. The advantage and disadvantage of single bridge probe and double bridge probe is briefly introduced in the paper. The necessity of the relationship between the two probes is explained. Based on two in situ test projects, a great deal of test data is obtained. By making use of statistic method, the empirical formulae between the two probes are given, and the applicability of the formulae also studied.
