摘要
在萧甬铁路增建二线工程中,对软土路堤地基采用粉喷短、密桩(桩长5.0m、桩间距1.0m)与长桩(桩长11.5m、桩间距1.25和1.35m)进行了对比试验,实践证明,短、密桩加固方案是技术上可行的,而且经济效益显著。
Powder mixing piles are used in the construction of the second line extention in Xiao-Yong railway. Comparison tests between two groups of different lengths and spacings of piles (i.e. length=5m, spacing=1m and length=11.5m, spacing=1.25~1.35m) were carried out. It is found that the results are applicable technically and economically.
