摘要]某熱軋廠設(shè)備箱形基礎(chǔ)長約500m、寬4060m,底面積巨大。熱軋生產(chǎn)線設(shè)備標(biāo)高精度對基礎(chǔ)差異沉降要求非常嚴(yán)格。采用樁基容易滿足對熱軋?jiān)O(shè)備箱形基礎(chǔ)差異沉降的要求,但耗資巨大;不采用樁基則節(jié)省投資,但存在后期差異沉降較大的風(fēng)險(xiǎn),從而影響生產(chǎn)。對樁基方案與強(qiáng)夯地基處理方案進(jìn)行了比較,并在各自基礎(chǔ)沉降完成全過程期間(包括生產(chǎn)階段),對工期、費(fèi)用、生產(chǎn)風(fēng)險(xiǎn)進(jìn)行比較,綜合評估這兩種地基處理方案的優(yōu)劣。

關(guān)鍵詞]箱形基礎(chǔ); 樁基; 強(qiáng)夯地基; 差異沉降; 生產(chǎn)階段; 工期; 費(fèi)用

Abstract: Equipment box foundation of a hot strip mill has a large area with 500 meters length and 4060 meters width. Hot strip mill equipment’s elevation accuracy calls for strict requirements for the differential settlement of the foundation. The pile foundation is easy to satisfy the requirements of differential settlement, but the cost is huge. Investment is saved if pile foundation is not used, but the differential settlement is a big risk and it will affect production. The construction period, cost and production risk of the pile foundation and the dynamic compaction ground foundation were compared in the whole process of foundation settlement period (including the production stage) to comprehensively evaluate the pros and cons of two foundation treatments.

Keywords: box foundation; pile foundation; dynamic compaction ground foundation; differential settlement; production stage; construction period; cost
