摘要
文中以福建省龙岩市某矿山浮选尾矿脱水工程 3 栋单层丙类厂房为例,对强夯置换法在素填土软弱地基施工中的应用进行分析.结果表明,按照试夯后的强夯方案参数对施工场地进行三遍点夯和满夯,经处理后的地基均满足承载力fak≥250 kPa且压缩模量Es≥25 MPa的要求.
Abstract
In this paper,the application of dynamic consolidation displacement method in the construction of weak foundation of plain filled soil is analyzed by taking 3 single-storey class C workshops of a mine flotation tailings dewatering project in Longyan City,Fujian Province as an example.The practical results show that the three pass point tamping and full tamping are carried out according to the parameters of the dynamic tamping scheme after the test,and the treated foundation can meet the requirements of the treatment bearing capacity fak≥250 kPa and the compression modulus Es≥25 MPa.
