摘　　要：电梯井在基坑开挖时,由于开挖深度比较深,很容易发生土方塌方事故。事故的原因常与不合理的施工方式有关,同时不合理的围护方案设计也是事故发生的主要原因。结合某实际工程发生的电梯井开挖过程中的塌方实例,剖析工程事故发生的原因及处理措施,提出合理的基坑支护结构选型、设计、施工是避免此类事故的前提。In the excavation of foundation pit of the elevator shaft, it is prone to collapse for the deep excavation.The cause of the accident is often related with the unpractical construction method. The unreasonable design of foundation pit is also the main cause. Combined with a practical engineering, the reason and treatment measures of engineering accidents during the excavation are analyzed. It presents that the reasonable foundation pit supporting structure selection, design and construction are the premise of avoiding such accidents.
