摘要
在50 kpa、100 kpa、150 kpa、200 kpa四种固结压力下,分别对双王城水库坝基土原状土样进行了动三轴试验,得到了最大动剪切模量Gmax和GGdmax γd曲线以及λλmax γd曲线,可供岩土和其他水利工程的地震安全性评价工作参考和借鉴。
Under the four kinds of concretions pressure of 50kpa,100kpa,150kpa and 200kpa,the experiment of dynamic triple axis has been carried out on the original foundation soil of dam,and we have deduced out the curves on maximum dynamic shear modulus and dynamic damping of foundation soil of dam.The experiment result can be a reference for the earthquake security valuation of other irrigation engineering.
