clayey sand

The waveform property,frequency property and relationship between porosity and acoustic attenuation ratio of the sediments under low and high frequencies were obtained by further processing of the physical and acoustic properties of clayed silt.

对黏土质粉砂的物理性质和声学性质作了相关处理,得到了在高、低两种测量频率下该类型沉积物的波形特性、频谱特性和与沉积颗粒因素有关的孔隙度对声衰减比的影响。

The paper carried out research on characteristics of grit with weak expanded clay from mineral composition, grain gradation, dilatability, compaction, permeability and strength.

针对燕山水库弱膨胀黏土质砂砾岩能否作为坝体填料这一问题,从矿物组成、颗粒级配、膨胀性、压实性、渗透性、强度等方面对其工程特性进行了研究。
