1975～1978年,我们在山西省晋南地区4个工厂的十余万平方米建筑物的地基加固中,采用了硅化加固独立基础下地基的方法,至今效果良好。加固后的地基承载力比天然地基提高3～7倍,并消除了湿陷性。它与一般新近堆积湿陷性黄土地基加固的垫层法、扩大基础底面积、井柱和钢筋混凝土预制桩抬基等加固方法相比,具有可维持继续生产,操作安全,施工工期短,劳动强度低,节省三大材料等优点。硅化加固地基可按设计要求加固到各种深度,加固土体坚硬稳定,呈柱状或组合成其他形状,加固后的地基可单独或与天然地
From 1975 to 1978, in the foundation reinforcement of more than 100,000 square meters of buildings in four factories in Jinnan, Shanxi Province, we adopted a method of silicification to strengthen the foundation under the independent foundation, and we have achieved good results so far. After the reinforcement, the bearing capacity of the foundation is increased by 3 to 7 times than that of the natural foundation, and the collapsibility is eliminated. Compared with the reinforcement methods such as cushioning method for newly collapsible collapsible loess foundations, the expansion of base area, wellbore, and prefabricated pile lifting foundations for reinforced concrete, it can maintain continuous production, operate safely, and the construction period is short. Low strength, saving three major materials and other advantages. Siliconized reinforced foundations can be reinforced to various depths according to design requirements. Reinforced soils are hard and stable, pillared or combined into other shapes. The reinforced foundation can be used alone or naturally.
