行车工况下地下室顶板受力分析研究

Research on Basement Roof Stress Analysis Under Driving Condition

在施工期间,大型施工车辆在地下室顶板上行走的情况很常见,但往往因设计和施工时对此工况下的实际受力情况考虑不全,而引起地下室顶板坍塌、渗漏等事故。结合南通R19026项目二标段地下车库顶板行车工况下地下室顶板受力分析实例,针对施工期间混凝土罐车在行走线路上对板、梁、柱各构件最不利布置情况进行受力分析,以便后期对不利构件加固提供依据。

During construction,it is common for construction vehicles to walk on the roof of large basements,but there are many accidents such as roof collapse and leakage of basements due to incomplete consideration of the actual stress in design and construction.The stress analysis of the basement roof under the driving condition of the underground garage roof in the second bid section of Nantong R19026 project is combined to analyze the stress of the most common concrete tank truck on the most unfavorable layout of the plate,beam and column components on the traveling line during construction,so as to provide a basis for the reinforcement of unfavorable components in the later period.
