摘　　要：通过调查分析施工荷载特性和地下室顶板极限承载力影响因素,利用荷载规范研究结论,简化地下室顶板车行荷载对顶板结构受力影响的计算方法,并以兰州市某高校公寓楼地下室顶板为研究对象进行实体验证。在顶板荷载设计基础上,通过顶板增加覆土、利用地下室顶板未拆除的钢管架支撑等措施,作为施工临时道路,可满足施工阶段施工车辆满载行车需要。在此基础上,综合分析评估了地下室顶板采取覆土及加固措施可行性及注意事项,为其它工程的后期建设施工提供了合理的计算方法和评估依据。According to the investigation and analysis of the construction load characteristics,and the factors of the basement roof ultimate load carrying capacity,simplified the calculation method of the influence of vehicle loads on the structure of the basement roof with the study conclusions of the load code for the design of building structures,and the basement roof of an apartment building in Lanzhou city is used as the research object for physical verification.On the basis of the load design of the roof,it can meet the needs of construction vehicles fully loaded during the construction stage through approaches such as adding the soil cover of the roof and using the cuplock steel tubular scaffolding that has not been removed from the roof of the basement as a temporary road for construction.On this basis,the feasibility and precautions for covering and reinforcement measures of the basement roof are comprehensively analyzed and evaluated,which provides a reasonable calculation method and evaluation basis for the other construction projects.
