在工程建设中常有各种建筑物座落在软土地基上,一般地基都要进行加固。加固软土地基的方法很多,其中有一种简便快速的方法叫做振动水冲碎石桩法。简称振冲桩,是利用振动和水冲在软土地基中就地振制碎石桩,此法在国外已有近半个世纪的发展历史,七十年代进入我国,1986年我们在某区3~#、4~#、5~#接转站的3000m~3拱顶金属油罐的地基处理中采用了这一技术,取得了很好的效果。3~#、4~#、5~#接转站所处地区的土壤为可塑
In the construction of the project, various buildings are often located on soft soil foundations. Generally, the ground should be reinforced. There are many ways to reinforce soft soils, and there is a simple and fast method called vibrating water and gravel piles. Abbreviated as vibrating piles, which uses vibrating and water flushing to shake the piles in place on the soft ground. This method has been in the development history of nearly half a century in foreign countries. It entered China in the 1970s and we in a certain area in 1986. This technique was adopted in the foundation treatment of a 3000m~3 dome metal tank at the 3~#, 4~#, and 5~# transfer stations, and achieved good results. The soils in the 3~#, 4~# and 5~# transfer stations are plastic
