基坑栈桥面板土方车等效荷载取值研究
发布时间：2018-12-12 13:16
【摘要】：土方车是行驶于基坑施工栈桥上的主要施工车辆。但对于栈桥面板在土方车作用下的等效荷载,我国现行《建筑结构荷载规范》中尚未作出规定。综合考虑了土方车数量、栈桥面板跨度、厚度等因素,分析了栈桥面板分别采用单向板和双向板时土方车轮压的不利布置,使用ABAQUS有限元软件确定了土方车的等效均布荷载值,并提出了相应的设计建议,其结果可供工程设计参考。
[Abstract]:Earth-moving vehicle is the main construction vehicle driving on the foundation pit construction trestle. However, the equivalent load of trestle face slab under the action of earthmoving vehicle has not been stipulated in the current Code of Building structure load in China. Considering the factors such as the number of earthwork vehicles, span and thickness of trestle deck, the unfavorable arrangement of earth wheel pressure is analyzed, and the equivalent uniform load value of earthwork is determined by using ABAQUS finite element software. The corresponding design suggestions are put forward, and the results can be used for reference in engineering design.
