目前，挡土墙的加固主要采用锚杆、锚索、墙趾加固等被动加固措施，而很少考虑到土压力系数等问题。为此，结合工程案例，根据库伦土压力原理，对挡土墙后填土注浆施工加固措施进行了探讨，以期达到加固效果。结果表明，在墙后填土区进行灌浆，可以有效提高土体的物理机械性能，提升挡土墙加固力。

Abstract:
At present,passive reinforcement measures such as anchor bolt,anchor cable and toe reinforcement are mainly adopted for reinforce- ment of retaining walls,while the earth pressure coetfficient is rarely taken into account.Therefore,the reinforcement measures of backflling &. grouting behind the retaining wall are discussed,based on actual engineering cases and citing the Coulomb Earth Pressure Principle,in order to achieve the reinforcement effect.The result shows that the physical and mechanical properties of the soil mass have been effectively enhanced by grouting in the backfill area behind the retaining wall,which becomes further strengthened accordingly.
