摘要
共振柱仪是测量土在应变幅低于10^(-4)时的动剪切横量和阻尼比的重要手段之一.经过几十年的应用发展,已为国内外广泛使用.本文介绍国内最近研制成功的新型GS-1型共振柱试验机的基本原理、结构和特点.该仪器以简单的结构实现了各向不等压的固结应力条件.
The resonant-columu apparatus is one of the important devices for obtaining the dynamic shear modulus and damping ratio of soil when the strain amplitude is less than 10^(-4) rad. This kind of Apparatus have now been widely used all over the world through several decades development. This paper introduces the basic principle, structure and advantage of the new GS-1 Resonant-Column Apparatus, Which has been recently developed in China. The cosolidation stress condition of unequal pressure in three directions has been realized by means of this new type device in its simple structure.
