山西省化肥厂地处湿陷性黄土地区,厂地土层为黄土状亚粘土,地表下深12M左右以内为Q_4,Q_3新黄土,都具有湿陷性,其下为很厚的Q_2老黄土,不具湿陷性。地下水埋深17—20M。为了消除湿陷性,改善提高地基土的物理力学的指标,满足引进装置对地基要求变形小,承载力大的严格要求,第二化工建设公司进行了地基处理试验,首创了625FM——400FM的高能量强夯
Shanxi Fertilizer Plant is located in the collapsible loess area. The plant soil is loess-like sub-clay. The depth of the subsurface is about 12m or less, Q_4, and Q_3 new loess, all of which are collapsible. The bottom is thick Q_2 old loess. , not collapsible. Groundwater depth 17-20M. In order to eliminate the collapsibility, improve the physical-mechanical index of the foundation soil, meet the stringent requirements of small deformation and large bearing capacity of the imported equipment, the second chemical construction company carried out the foundation treatment test and pioneered the 625FM-400FM. High-energy powerful
