摘要
软土地基不经过处理直接修建储罐群,在充水预压过程中容易产生不均匀沉降。针对一实际工程事故,运用FLAC^(3D)数值模拟软件对工程事故原因进行了分析,证明充水过快、产生较大超孔隙水压力是储罐群地基产生不均匀沉降的主要原因。根据工程现场情况,提出并采用合理的纠偏方案,达到了理想的纠偏效果。
When storage tank is constructed in soft soil area without treatment, the uneven settlement always occurs in the preloading process. Based upon a case study of a real project accident, the causes of the accident are analyzed with FLAC^3D numerical simulation software. It proves that the excessive pore water pressure resulting from fast water filling is the major cause of uneven settlement. Appropriate corrective programs based upon site conditions are proposed and applied, satisfactory results have been achieved.
