马尔代夫珊瑚砂孔隙比试验研究及无核密度仪应用初探
摘要:马尔代夫珊瑚砂因其特有的形状不规则、微孔丰富等特性,不仅在颗粒表面有不规则敞口孔隙,在颗粒内部还有封闭内空隙,与传统的石英砂差别较大。在珊瑚砂物理和化学特性分析的基础上,提出一套行之有效的确定珊瑚砂孔隙比的方案,并通过实测资料进行计算。同时,在工程实践中,采用无核密度仪,不仅数据更加可靠,同时大大提高了工作效率。
Abstract:The typical characteristics of the coral sands in Maldives are irregular shape and abundant micropores,with irregular opening pores on particle surfaces and closed pores in particle interior,which is very different from the quartz sands.Based on the analyses of the physical and chemistry characteristics,an effective method to measure the void ratio of the coral sands is proposed,and calculation has been done with the actual measurement.Besides,the application of the electrical density gauge in engineering practice has the benefits of increasing the data reliability and improving the work efficiency.
