摘要:

根据新疆乌拉泊水库副坝防渗墙掺粘土混凝土不同龄期的室内徐变试验结果，拟合了该混凝土材料弹性模量、徐变度及应力松驰系数等的计算式，可用于观测应力计算。

Creep test for concrete mixed with clay

CHEN Can-ming,HUANG Wei-Ian,ZHANG Run-jie,TANG Yun-qing

Abstract:

Some indoor creep tests for concrete mixed with clay with different ages of the impervious core of the auxiliary dam of Wulapo Reservoir are carried out. According to the experiment results, calculation formulas of the elastic modulus, creep degree and stree relaxation coefficient of the concrete are fitted, and can be used to calculate the measured stress.

Key words: elastic modulus,creep,relaxation coefficient,clay,concrete,
