| 摘 要： | 用强夯处理大厚度的高饱和细粒土地基一般比较困难,但用碎石桩加强夯联合工法处理该类地基,能得到很好的加固效果。碎石桩的作用机理除挤土、置换和加筋形成复合地基外,由于其颗粒粗、孔隙大、渗透性好、密度大等特点,在与强夯组成联合工法时,还可起重要的排水、隔振聚能和压重作用。

| Abstract: | It is generally difficult to treat a thick foundation of high-saturated fine-grained soil by dynamic consolidation.However,using a method combined gravel pile with dynamic consolidation can achieve good treatment effect in this foundation.The treatment mechanism of gravel pile not only lies in its functions of squeezing soil,replacement and reinforcement so as to form a composite foundation,but also includes the rules of drainage,vibration isolation,energy gathering and soil stabilization when applied jointly with dynamic consolidation method due to its coarse grain,big pore,good penetrability and high density. |
