摘要

为了研究冻土-混凝土接触面的力学特性，开发了一种低温动荷载直剪仪，它是在普通直剪仪框架的基础上，安装了动力加载系统和温度控制系统。该装置能够保证在负温条件下对冻土进行动荷载直剪试验，从而测定冻土的动力学参数。为了研究寒区冻土与混凝土构筑物的相互作用，使用该仪器进行了一系列的多因素接触面动直剪试验，试验结果表明了冻土-混凝土接触面在动荷载作用下的行为特征，多因素对比试验则揭示了接触面动剪强度的影响因素和变化规律。

Abstract

In order to study the mechanical properties of frozen soil-concrete contact interface

a kind of dynamic direct shear system for frozen soil was developed. Based on the framework of a static shear apparatus

it was installed with a dynamic loading system and a temperature control module. With this dynamic direct shear system

dynamic shear tests of frozen soil under specified temperatures are able to be operated. Then dynamic parameters of frozen soil are measured. By placing concrete blocks in half of the shear box and frozen soil in the other

we operated a series of dynamic shear tests on the frozen soil-concrete contact interface. The results show some behavioral characteristics of the contact interface under dynamic loads

multi-factor comparison revealed the influencing factors and the variation.
