珠海富水软土小应变硬化参数试验研究
Experimental study on parameters of small strain hardening model of Zhuhai soft soil with high water content
摘要
Abstract
This study completed a series of laboratory tests to obtain all HSS model parameters of water-rich soft soil in Zhuhai area,and analyzed the proportional relationship between the modulus of key parameters Eref50,Erefoed,Gref0 and Erefur,providing an important supplement to the HSS model parame-ters of different soil layers in Zhuhai area.Compared with the results in the literature,it is found that the small strain reference shear modulus Gref0 of the clay in Zhuhai area is higher than that of the sand.Compared with other coastal areas such as the Yangtze River Delta,the water content of Zhuhai clay is higher,and its reference secant modulus Eref50,reference loading and unloading modulus Erefur,reference tan-gent modulus Erefoed and reference shear modulus Gref0 are lower.关键词
