太钢2250热轧工程主轧线设备基础设计所在持力层地质条件不能满足设备安装和生产工艺要求，必须进行技术处理，保证基础的沉降量满足设备运行的要求。通过多方案的技术分析、比较和论证以及地基的设计计算和施工技术的介绍，确定砂砾石垫层地基换填＋降水预压固结地基处理方案。在施工中因地制宜，采用天然级配砂砾石作为换填料，既保证了质量，达到设计要求，又充分利用当地资源，降本增效。为日后类似工程积累了成功经验。
太鋼2250熱軋工程主軋線設備基礎設計所在持力層地質條件不能滿足設備安裝和生產工藝要求，必鬚進行技術處理，保證基礎的沉降量滿足設備運行的要求。通過多方案的技術分析、比較和論證以及地基的設計計算和施工技術的介紹，確定砂礫石墊層地基換填＋降水預壓固結地基處理方案。在施工中因地製宜，採用天然級配砂礫石作為換填料，既保證瞭質量，達到設計要求，又充分利用噹地資源，降本增效。為日後類似工程積纍瞭成功經驗。
