Abstract

The goal of this study was to improve the understanding of the soil-structure interaction mechanisms at the interface of bored concrete piles cast in sandy soils. In addition, this study aimed to quantify the interface shear strength and identify the factors that influence the response. Roughness measurements and direct shear tests were performed at the interface between two samples of sand (medium and coarse) and concrete cured under stress. The influence of the mean grain diameter, relative density, water content, concrete curing time and normal stress on the interface shear strength were statistically analyzed. The results showed a consistent behavior with the technical literature, but with higher values, which can be attributed to the concrete curing time, a factor not studied by other authors.

应力固化颗粒土与混凝土界面抗剪强度分析

本研究的目的是提高对砂质土中钻孔灌注桩界面土-结构相互作用机制的认识。此外，本研究旨在量化界面抗剪强度，并确定影响响应的因素。在两个砂(中、粗)和混凝土试样的界面处进行了粗糙度测量和直剪试验。统计分析了平均粒径、相对密度、含水量、混凝土养护时间和正应力对界面抗剪强度的影响。结果与技术文献一致，但数值较高，这可归因于混凝土养护时间，这是其他作者未研究的因素。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
