[摘要]  截取热轧厂房地下室中的一部分，采用SOFISTIK有限元软件对其进行三维计算分析。计算中将桩简化为线弹性的弹簧单元作为地下室承载体系，分析了不同部位桩反力以及不均匀沉降的分布情况。根据计算结果，对地下室顶、底板以及侧壁的受力状况进行了分析，并与常规计算进行对比，提出了合理建议。

Abstract:  Part of a hot steel rolling plant basement was calculated and analyzed by SOFISTIK finite element software. In the calculation, group of piles were simplified to liner elastic springs. Based on the calculation results,reaction and displacement of piles in different zones were analyzed. Forces of top, bottom plates and side walls in the result were compared with routine methods. Therefore reasonable suggestions are brought forward.
