[摘要]  截取熱軋廠房地下室中的一部分，采用SOFISTIK有限元軟件對(duì)其進(jìn)行三維計(jì)算分析。計(jì)算中將樁簡(jiǎn)化為線(xiàn)彈性的彈簧單元作為地下室承載體系，分析了不同部位樁反力以及不均勻沉降的分布情況。根據(jù)計(jì)算結(jié)果，對(duì)地下室頂、底板以及側(cè)壁的受力狀況進(jìn)行了分析，并與常規(guī)計(jì)算進(jìn)行對(duì)比，提出了合理建議。

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.
