湿陷性黄土地基硅化法加固方法是五十年代由前苏联引进的技术,目前已被我国湿陷性黄土地区广泛用来处理地基或加固建筑物基础。具有工艺简单、适用范围广、成本低、工期短、效果明显的特点。各地区都有成功的例子。但用硅化法结合灰砂桩加固既有建筑物基础尚不多见,我们洛阳建筑段对洛阳车辆段检修库牛腿柱杯型基础下沉采用此法,较成功地完成了加固工作。一、工程概况洛阳车辆段检修库,建筑面积3896m_2,属高低跨大型工业厂房,七十年代建造,1993年12月洛阳建筑段在巡检中发现②轴线至⑤轴线间低跨
The collapsible loess foundation silicification method is a technique introduced by the former Soviet Union in the 1950s. It has been widely used in China’s collapsible loess area for foundation treatment or foundation reinforcement. With a simple process, a wide range of applications, low cost, short duration, the effect is obvious. There are successful examples in all regions. However, it is rare to use the silicification method combined with the lime sand pile to reinforce the existing building foundation. This method was adopted by Luoyang Building Section for the sinking of the cowhide column basement of the Luoyang Vehicle Depot, which successfully completed the reinforcement work. First, the project overview Luoyang vehicle depot maintenance, construction area of 3896m_2, is a high-low across large industrial plants, built in the seventies, December 1993 Luoyang building inspection found ② axis to ⑤ low-span
