摘要

课题组以往的研究成果表明，板位是影响新型混凝土膨胀板桩（NT-CEP桩）群上浮承载力和桩周围土体破坏状态的主要因素。本研究开发了未扰动土体拉伸试验的可视化半截面桩小型模型和 ANSYS 有限元软件对比分析双桩小型试验模型，以及包括角桩、边桩和中桩在内的双桩、四桩、六桩和九桩模型。确定了板位对竖向拉力作用下 NT-CEP 桩群的位移、应力和承载机理的影响，进一步完善了 NT-CEP 桩群的设计理念，为其广泛应用提供了有力的理论支持。

Influence of Plate Position on Uplift Failure State and Bearing Capacity of NT-CEP Pile Groups

The previous research results of the research group demonstrated that the plate position is the main factor affecting the uplift bearing capacity of the new type of concrete expanded plate pile (NT-CEP pile) group and the failure state of the soil around the pile. In this study, the visual half-section pile small-scale model of undisturbed soil tension test and ANSYS Finite Element Software comparative analysis two-pile small-scale test model and two-, four-, six-, and nine-pile models, which included the corner, side, and middle piles, were developed. The effect of the plate position on the displacement, stress, and bearing mechanism of the NT-CEP pile group under vertical tension was determined, which further improved the design concept of the NT-CEP pile group and provided strong theoretical support for its widespread application.

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.
