某场区黏土质砂液化综合判别研究

Liquefaction Discrimination of Clayed Sand in Certain Field

通过室内试验对场区黏土质砂的物理力学性质进行详细分析,采用标准贯入试验、剪切波速试验、扁铲侧胀试验及室内动三轴试验对黏土质砂进行液化判别,分析了各种液化判别方法液化判别结果差异性的原因,提出适用于黏土质砂液化判别的方法,并使用该方法对场区黏土质砂进行了综合液化判别。

Through laboratory tests,the physical and mechanical properties of clayey sand were analyzed in detail.The stand-ard penetration test,shear wave velocity test,flat dilatometer test and dynamic triaxial test were conducted to identify the liquefaction of clayed sand.The reasons for the difference of liquefaction identification results of various liquefaction discrimination methods are analyzed,and a suitable method for liquefaction identification of clayed sand is proposed.The comprehensive liquefaction discrimina-tion of clayey sand in the field is carried out.
