组合锤法在山区填土地基处理工程中的应用

Application of combination hammer in the treatment of backfill soil in mountainous areas

组合锤法地基处理技术能有效处理深厚填土地基。结合福建省龙岩市某工业园区一新建项目的地基处理工程实例,研究了组合锤法在山区填土地基处理工程中对深厚填土地基的影响,结果表明:经组合锤法处理后,素填土地基的承载力和密实度都得到很大的提高,地基满足设计要求,组合锤法地基处理技术能较好地弥补普通强夯法无法处理深层填土的缺陷。

Combination hammer is an effective method for the ground treatment of deep-thick backfill soil.Based on the ground treatment practice of a new project in the industrial park of Longyan,Fujian,this article studied the influence of combination hammer on the ground treatment of deep-thick backfill soil.The result showed:combination hammer can effectively improve the characteristic value of subsoil bearing capacity and compression modulus;the foundation can meet the design requirements;combination hammer is a good remedy for the defects of ordinary dynamic compaction which can not handle the deep fill soil.
