预应力锚杆因出色的维稳能力及巨大的经济效益,在岩土锚固工程中扮演着重要角色.然而,预应力锚杆的长期性能常因周围恶劣岩土环境的腐蚀而不断退化.为了探究预应力锚杆在模拟岩土环境中的锈蚀机制,通过开展室内加速腐蚀试验,基于电化学阻抗谱及电化学极化曲线分析了处于弱酸、通氧条件下的预应力锚杆腐蚀损伤时变行为,以及该环境下预应力锚杆锚固力与腐蚀速率的关系.结果发现,试验过程中预应力锚杆均未出现明显钝化,浸泡前期处于未通氧环境下预应力锚杆的电化学阻抗谱为一半径很大的容抗弧,预应力锚杆腐蚀不明显,锈蚀受电荷传递控制,中后

基于一种新的土体非线性压缩模型,建立了考虑瞬时荷载和变荷载的一维非线性固结方程.采用有限差分法获得了该固结方程的解,并通过与半解析解对比验证了差分法解的可靠性.基于该解,详细讨论了外荷载、土体初始压缩系数及压缩指数与渗透指数比值Cc/Ck对土体固结和沉降特性的影响.结果表明:Cc/Ck通过影响固结系数进而影响到土体固结速率,固结系数随Cc/Ck取值的减小而增大,因此土体固结速率随Cc/Ck取值的减小而增大;当土体初始压缩系数很小时,土体压缩性很小而接近弹性,此时可以忽略土体的非线性而直接采用Terza-g
