为了探讨微生物诱导碳酸钙沉积(MICP)在实际工程中的应用方法,尝试注浆管MICP加固土体,即在土体中插入不同分布密度注浆孔的注浆管,将菌液和胶结液通过注浆管注入土体中,从而形成加固体,并通过对比试验,研究注浆管MICP的加固效果。试验结果表明,经过注浆管MICP处理,能形成完整的且强度较高的固化砂柱,并且固化砂柱的强度比较均匀。 相似文献

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
