摘　　要：由于帷幕注浆和深层搅拌桩防渗在技术与经济上具有一定的优势,在填埋场工程及污染场地中常作为首选方案,现有室内试验都是采用纯黏土作为隔离屏障。但在实际工程中水泥土垂直隔离屏障却应用得更加广泛,而在国内外针对水泥土屏障的研究却鲜有报道。拟通过大型模型试验来分析屏障厚度和水泥掺量对隔离效果的影响进行初步研究。As the curtain grouting and deep mixing vertical barrier curtains were of certain advantages in technology and economy, and they were preferred schemes in the landfill engineering and pollution construction sites, pure clay as an isolation barrier was often used in the present laboratory tests, but in the actual engineering, cement soil vertical isolation barrier was widely applied, but it was rarely reported domestically. Through a large model test, the author analyzed the thickness and cement mixing content of the barrier and made a preliminary study on the isolation effect.
