The influence of water boundary conditions on pore pressure was studied by one-dimensional electroosmotic consolidation test, and the effects of electroosmosis, pore water pressure,settlement and electroosmotic flow were monitored and analyzed.The results show that the boundary conditions of electroosmotic water have a significant effect on the pore water pressure and improving effect. Negative pore water pressure without auxiliary water is far greater than the replenishment. The measured data show that improvements in experiments without replenishment are also better. The calculation of Esrig solution of the pore water pressure is consistent with the measurement data in the watersupplementing test and is very different from the measurement data in the test without rehydration. Considering the impact of water boundary conditions is the key to electroosmosis experiments and applications.  相似文献

电渗法是一种重要的处理软土的方法。电渗固结理论假设土是完全饱和的,而实际工程中处理的土多为非饱和土,电渗加固效果仍尚待研究。为此,采用自制的一维加固电渗仪,进行不同饱和度黏土的电渗对比试验,通过比较试验中电流、排水量、沉降、含水率、最终强度等指标的变化情况,研究非饱和土的电渗加固效果。结果表明,从电渗结束后土体强度增长幅度上看,含水率越低的土样强度增长幅度越小。与饱和土相比,电渗对非饱和土有一定的加固效果,但是加固效果不及饱和土。  相似文献
