中文摘要：
试验设计了混凝土压应力和弯曲应力加载装置，利用弹簧变形储能提供持续稳定应力，研究了应力作用下混凝土电通量的变化规律。结果表明，混凝土强度等级越低，渗透性越大，混凝土自身密实程度及裂缝决定其渗透性大小。在压应力作用下，当应力比小于0.4时，电通量随应力比的增大而减小，而应力比大于0.4时，电通量则随应力比增大而快速增大。弯曲应力作用下，电通量随应力比的增大而不断增大。
英文摘要：
Experimental designed a loading device for concrete under compressive load and bending load ,using the spring deformation energy storage to provide a steady load force,studied the electric flux change rule of concrete under the action of stress.The results show that the concrete strength grade is lower,the greater the permeability,dense degree of concrete itself and crack size to determine the perme-ability.Under the effect of compressive stress,when the stress ratio is less than 0.4,the electric flux decreases with increasing of stress ra-tio,and stress ratio greater than 0.4,the electric flux increases with the increase of stress ratio and fast.Under the action of bending stress and electric flux increased with the increase of the ratio of stress.
