Based on a practical case of cement soil replacement construction at the foundation of an inverted siphon, Middle Route Project of South to North Water Diversion, the cement soil replacement technology with high cement ratio up to 15%, was conducted. Large amount of indoor and field tests and on-site check data in the construction show that for the foundation soil layer under unfavorable geological conditions, the cement replacement works accomplished by gird cement pavement method and high content cement mixing by machinery has the characteristics of high construction speed, easy construction and better construc-tion effect.
