Discussion on common problems of pore canal in pre-stressed concrete bridge 预应力混凝土桥梁孔道常见问题探讨
The development of the pore pressure and deformation of a canal slope excavated in unsaturated expansive soil in Zaoyang City during artificial rainfalls is simulated by use of the simplified consolidation theory of unsaturated soil. The computed results are qualitatively agreeable to the observed data. 应用非饱和土简化固结理论,模拟枣阳膨胀土渠道边坡在人工降雨过程中孔隙压力变化和变形的发展过程,数值计算结果在定性上与实际观测资料一致。
The results indicate that most Sn2+ permeate into the pore canal of bamboo charcoal by restoring to the original state Sn. 结果表明:Sn2+大部分进入到竹炭的孔道中,并且被还原为单质Sn。
