【摘要】：土方車是行駛于基坑施工棧橋上的主要施工車輛。但對于棧橋面板在土方車作用下的等效荷載,我國現(xiàn)行《建筑結(jié)構(gòu)荷載規(guī)范》中尚未作出規(guī)定。綜合考慮了土方車數(shù)量、棧橋面板跨度、厚度等因素,分析了棧橋面板分別采用單向板和雙向板時土方車輪壓的不利布置,使用ABAQUS有限元軟件確定了土方車的等效均布荷載值,并提出了相應(yīng)的設(shè)計建議,其結(jié)果可供工程設(shè)計參考。
[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.
