摘要
针对目前混凝土材料研究领域中的热点———开裂问题 ,文章就国外在单轴约束试验方法上取得的进展做一综述 ,主要介绍开裂试验架和应力试验机的方法和原理 ,同时涉及国外在该领域的研究概况。作者认为 :开发这类试验装置对我国土木、水利。
Aim at the hot issue in the field of concrete materials research-cracking problem , this paper introduces the advances in the uniaxial restrained test method abroad. The main content deals with test methods and principle analysis of concrete cracking frame and Stress Test Machine. This paper comes to the conclusion that it is necessary to establish such test apparatus and methods for research and construction of the concrete structures in civil, hydraulic and hydropower, and building engineering in China.
