掺砂量对中度盐碱土壤水力特性及溶质运移过程的影响

Shuitu Baochi Xuebao
[目的] 为探究不同掺砂量对中度盐碱土壤水力特性和溶质运移过程的影响。[方法] 采用室内土柱试验,设置4种掺砂比例CK (掺砂0)、B1(掺砂10%)、B2(掺砂15%)、B3(掺砂20%),研究中度盐碱土壤在不同掺砂量条件下的土壤水力特性和溶质运移过程变化规律并进行模型模拟。[结果] (1)掺砂量在0~20%内,中度盐碱土掺砂明显影响土壤水分特征曲线变化,掺砂比例越大,曲线越靠近Y轴。在任一吸力条件下土壤含水率表现为CK＞B1＞B2＞B3。且掺砂比例越大,土壤小孔隙数量越多,微小孔隙减少 ...

T形PEC柱抗震性能的数值模拟分析

Jianzhu Gangjiegou Jinzhan
利用ABAQUS软件对14个T形PEC柱进行低周反复加载模拟，分析不同参数对T形PEC柱抗震性能的影响规律。结果表明：T形PEC柱的滞回曲线呈饱满的平行四边形，且刚度退化稳定，耗能能力和延性良好；提高混凝土强度等级虽然可增大柱的初始刚度，但混凝土强度等级过高则会导致柱的延性降低，刚度退化加剧，抗震性能降低；在T形PEC柱内设置横向拉杆，且将x方向和z方向的横向拉杆相互焊接，有利于对混凝土形成套箍作用从而提高柱的抗震性能，但拉杆间距不宜大于150 mm ...
