真空预压与粉喷桩处理软基经济性比较研究

Economy Comparison of Soft Clay Ground Disposal between Vacuum Preloading and Dry Jet Mixing Pile

软土路基处理是高速公路建设过程中的难题,在对真空预压与粉喷桩两种处理方法在试验段上进行经济对比分析的基础上,对不同间距的粉喷桩与真空预压处理分别计算费用,计算出其临界桩长,有助于该方法的推广利用。

Soft clay ground disposal is a difficult problem in the freeway construction. This article analyses vacuum preloading and dry jet mixing pile disposal methods in economy contrastively in test section and calculates expenses of the different space between dry jet mixing piles and vacuum preloading in order to figure out critical length of the pile, aiming at spreading and application.
