摘　　要：检验桩的承载力,需要进行现场测试,测试方法的可靠性和测试数据的准确性十分重要。本文介绍了一种线法监测方式滑动测微计的原理及其在桩基测试中的应用。该方法可进行桩基的内部变形分布观测。工程实例表明,这种仪器是一种高精度、使用方便、在岩土工程领域具有广阔应用前景的仪器。Field monitoring is demanded in testing pile bearing capacity, so the reliability of test methods and the accuracy of monitoring data are very important. In this paper, a kind of new instrument named Sliding Micrometer as well as its principle and the application in pile testing, is introduced. The field of its application relates to the measurement for the inner deformation distribution of tested pile. Projects show it is a kind of high-precision and easyto-use instrument with extensity prospect in Geotechnical engineering.
