内置核心筒的预制边坡反力结构局压性能分析
Local compression performance analysis of prefabricated slope reaction structure with built-in core tube
摘要
Abstract
In order to solve the problems of heavy structural weight and poor local compression performance of joints in the current slope reaction structure,a prefabricated slope reaction structure with a built-in core tube is designed,the failure mode and bearing capacity were studied by indoor axial local compression test and finite element numerical simulation analysis.The results show that the structural cracks first develop from the diagonal of the local compression zone to the chamfer,and then develop obliquely from the chamfer to the bottom of the beam end,which is a typical"Wedge split-ting"failure mode.The diameter-thickness ratio decreases from 36.7%to 26.7%,the ultimate bearing capacity of the structure increases by 2.3%.With the decrease of the diameter-thickness ratio,the bearing capacity of the structure increases slightly.The local compression area ratio of the structure with a span of 1 m increases from 2.151 to 3.361,and the ultimate bearing capacity of the structure decreases by 31.5%.The local compression area ratio of the structure with 0.6 m span increases from 1.138 to 1.778,and the ultimate bearing capacity of the structure decreases by 28.9%.The bearing capacity of the structure decreases with the increase of the local compression area ratio.关键词
