摘要
对采用真空预压法处理的某排放碱渣的滩涂场地基加固效果进行分析,现场检测数据表明,经过100d的预压后,碱渣地基表面沉降量达到1 m以上,地基平均固结度超过85%,加固后碱渣地基含水量、孔隙比明显减小,地基承载力达到80 kPa,可满足建设场地的需要,说明采用真空预压法处理含碱渣层软基是可行的,可在类似的工程中应用.
In this paper,the method of vacuum preloading is applied to improve the tidal flat site of pilling up alkaline residue.The improvement effect is analyzed.The spot data presented the method is effective.After vacuum preloading of 100 days,the ground settlement of is more than 1.0 m,the degree of consolidation is over 85%,water content and void ratio of foundation soil are significantly reduced,the foundation bearing capacity can reach 80 kPa,it satisfy the demand of engineering practice.It is proved the technique of vacuum preloading is feasible to improve the tidal flat site of pilling up alkaline residue.
