| 摘 要： | 考虑地震活动对建筑破坏的影响以及当前房屋基础土方施工中计算得到的土方量与实际土方量之间的误差较大,后期造成沉降、施工耗时等问题。提出房屋基础土方施工方法并应用到震后重建区域,分析房屋基础土方施工场地积水、橡皮土和密度不达标的问题,提出相应的解决措施,通过计算单位面积的土方量获得房屋基础土方施工现场的总土方量,根据土方量计算结果结合施工场地条件、工期要求和设计方案,采用navisworks软件和Revit软件构建三维模型,根据模拟结果调整并优化施工方案,完成震后重建区域中房屋的基础土方施工。实验结果表明,所提方法的土方量计算结果准确率高、可一定程度抑制由于地震造成的沉降,施工耗时少,整体的施工效率高。

| Abstract: | Considering the influence of seismic activity on building damage, the errors between calculated and actual quantities of earthwork are large in current earthwork foundation construction, resulting in settling and time-consuming construction at later stages. This paper puts forward a method for earthwork foundation construction and applies it to a reconstruction area after an earthquake. We analyzed the problems of water accumulation, rubber soil, and substandard density in the construction site, and proposed corresponding solutions. By calculating the quantity of earthwork per unit area, the total quantity of earthwork in the construction site building foundation was obtained. Using these calculated results, combined with the conditions at the construction site, the duration requirement, and the design scheme, Navisworks software and Revit were adopted to construct a three-dimensional model. According to the simulation results, the construction scheme was adjusted and optimized, and the foundation earthwork construction for the building in the post-earthquake reconstruction area was completed. The experimental results showed that the accuracy of earthwork calculation results with the proposed method is high, and that settling induced by earthquake can be restrained to a certain extent. The construction time is short and the overall construction efficiency is high. |
