摘要
深基坑工程是一项复杂的工程,涉及施工、结构和岩土等多个不同的工程领域。文章以某住宅小区工程为例,根据基坑支护方案,采用FLAC 3D 6.0有限元分析软件对基坑开挖及支护进行了数值模拟,并对比其实测结果,结果表明,在基坑周边采用止水帷幕并设组合钢管桩,有效减少了基坑变形及受力。基于此,文章提出了施工优化措施,旨在为类似工程实践提供参考和借鉴。
Deep foundation pit engineering is a complex engineering,involving multiple different engineering fields such as construction,structure and rock and soil.Taking a residential community engineering as an example,according to the foundation pit support scheme,FLAC 3D 6.0 finite element analysis software is used to carry out numerical simulation of the excavation and support of the foundation pit,and the actual measurement results are compared.The results show that using water-stop curtain and setting composite steel pipe piles around the foundation pit can effectively reduce the deformation and stress of the foundation pit.Based on this,construction optimization measures are put forward,aiming to provide reference for similar engineering practice.
