摘　　要：在深厚软土场地中,桩锚基坑失稳破坏范围往往较大,常被误以为是基坑深层滑移引起,因此,准确判断破坏模式,对后续采取有针对性的抢险加固措施至关重要。文章结合某桩锚支护基坑工程案例,针对基坑失稳现场破坏的特征,通过软件计算与结果分析,查明基坑失稳的原因,可为类似工程提供参考。In deep soft soil sites,the failure range of pile-anchor excavations is often large,and it is often mistaken for the deep sliding of excavations.Therefore,accurate judgment of the failure mode is critical for subsequent emergency reinforcement measures.For on-site destruction characteristics of excavations instability,this article combines a case of a pile-anchor supporting excavations project,and the cause of excavations instability was found out through software calculation and results analysis.It can provides a reference for similar projects.
