摘要
三清高速公路桥梁工程项目区内软土地基类型为湿陷性黄土,经分析明确其物理性质与化学性质,结合工程经验对湿陷性黄土采用碎石桩解决不同路段的软基问题,经标贯检测、触探检测证明均达到合格标准,取得了显著的效果。
The soft-soil foundation type in the bridge project area of Sanqing Expressway is collapsible loess.The physical and chemical properties of the collapsible loess are determined by analysis.Based on the engineering experience,gravel piles are used to solve the soft foundation problems of different sections of the collapsible loess.Both the standard inspection and penetration testing have reached the qualified standards and achieved remarkable results.
