摘要:
传统经验认为真空预压施工时,排水板选用通水量较大的型号有利于提高地基土的加固效果。结合真空预压处理悬浮状细颗粒的吹填土现场施工,分别采用A型、B型排水板进行真空预压加固,对加固过程中的真空度、表层沉降、孔隙水压力等数据进行监测的试验过程,并对加固完成后土样的含水率、十字板强度等进行了测试。研究表明,不同类型排水板对浅表层悬浮状吹填土的真空预压加固效果相当,并基于此结论将后续施工采用的B型排水板替换为A型,取得了良好的经济效益。
Abstract:
It’s considered traditonally that the larger discharge capacity types of band drains are prefered to be used to improve the reinforcement effect in vacuum preloading.Type A and Type B band drains were applicated in vacuum preloading of dredged fill foundation reinforcement consisted of suspended particles.The vacuum degree,surface settlement,pore water pressure were observed during experiment,and the water content,vane shear strength of soil were tested after the consolidation.The results show that the foundation using two type’s band drains achieved the same reinforcement effect.On base of the conclusion,the type B band drains were replaced with type A in subsequent project, that create more economic benefit.
