摘要： 随着经济发展的日益加快，城市建设越来越集中化。在城市内部进行高层建筑的基坑开挖必然会受到周边复杂环境的影响，因此在基坑周边环境影响下基坑开挖的合理方案选取就有着更高的要求。以某地区基坑开挖为案例，定量分析了基坑周边有汽车动荷载作用下二元结构边坡合理开挖方案。通过建立基坑开挖模型，模拟了分步开挖和分步跳挖两种开挖方式，分析得出分层跳挖是最有利于保持基坑稳定性的开挖方式。

Abstract: With the highspeed of the economic development, the urban construction is more and more concentrated.Highrise building foundation pit excavation is bound to be affected by the surrounding complex environment, therefore selecting the reasonable foundation pit excavation scheme has a higher request in the surrounding complex environment.Based on the case of the foundation pit excavation, this paper quantitatively analysis the reasonable slope excavation scheme with the cars dynamic loads around the binary structure.The stepbystep excavation and stepbystep jump dig methods are simulated by setting the model of slope excavation, and it is concluded that the most beneficial to maintain the stability of foundation pit excavation method is stepbystep jump dig.
