In.the presen. work, radon.gas con.en.ration. in.differen. dwellin.s in.Baghdad govern.rate are measured by usin. RAD-7 detector. The results have shown.that, the radon.gas con.en.ration. ran.ed between.(40.67 ± 3.1 Bq/m3) to (190.00 ± 2.7 Bq/m3) with an.average value (113.66 ± 30.2 Bq/m3);in.the first on. we draw the map radiation. for in.oor radon.gas con.en.ration. in.Baghdad govern.rate. We would like to men.ion.that the presen. study is con.idered to be very importan. an. vital because it is con.ern.d with people health an. safety in.the first place.

通过主应力旋转试验,研究了黄河饱和粉质土在不同初始固结角度ζ条件下的应变发展规律。结果表明,轴向、环向和扭剪应变表现出不同的模式,显示出ζ对粉质土的力学响应影响。特别是在ζ=90°时,轴向应变在第1次加载循环中表现为压缩行为,而环向应变则表现为拉伸行为。不同初始固结角度引起的各向异性在ζ=90°和ζ=60°附近开始显现。不同ζ值的应变波动趋势趋于稳定,其中ζ=90°和ζ=75°表现出相似性;而当ζ=45°时,表现出最大的波动性和应变幅值。除ζ=90°和ζ=60°外,大多数ζ角下的扭剪应变表现出相似性。体积应变突显了固结角度对土体各向异性特征的显著影响。随着初始固结角的增加,滞回曲线向左移动,表现出循环蠕变特性;在ζ=60°时,剪切应变几乎可以忽略。随着循环周期的增加,滞回环收缩,表现出剪切刚度的持续增强并最终稳定。该研究揭示了初始固结角度对饱和粉质土的力学特性的影响。
