沉积磷石膏的物理力学特性试验研究

沉积磷石膏的物理力学特性试验研究

摘要:磷石膏是磷酸生产过程中的副产品,目前的综合利用率尚不足40%,大部分需要堆存存放。受地形限制和经济效益考虑,中国主要为湿法堆存的山谷型堆场。依托柳树箐磷石膏堆积坝,针对沉积磷石膏首先开展了密度、含水率、渗透、土水特征和颗分等物理性质试验,然后开展了三轴cu、蠕变及动三轴等力学特性试验。试验结果表明:①沉积磷石膏的干密度与埋深没有相关关系;②沉积磷石膏不具有自然分级现象,但具有明显的各向异性;③沉积磷石膏具有较高的摩擦角和抗液化能力,但其蠕变变形较大、渗透比降较小。上述工作为分析磷石膏堆积坝的坝体稳定性提供了基础,对现行磷石膏库的运行管理以及新建工程的设计具有重要的借鉴意义。
