高能级强夯法在处理湿陷性黄土地基中的应用

摘要

High energy level ramming refers to that every ramming gives energy greater than 6 000 kN· m. Consolidating greater thickness wet-depressive loess by using this method can drastically improve soil strength and uniformity, overcome its wetness and depression. The effect of heavy ramming may very much depend upon selected operating methods and parameters. Cracks arising in ramming and ramming energy allocated everywhere should be taken into careful consideration.%高能级强夯一般指每单击夯击能大于6000kN·m强夯，用其加固处理大厚度湿陷性黄土地基，对提高地基土强度和均匀性，消除湿陷性具有明显的效果。施工工艺和参数的选择对强夯效果影响很大。施工中对夯击裂缝和夯击能分配问题应认真处理。
