摘　　要：针对广州地区地铁盾构施工端头井加固现状,介绍砂土地层盾构端头加固的主要方法和基本要求、加固体强度和稳定性的验算模式,结合某具体工程的地层条件,对加固效果进行了核算。On basis of the reinforcement situation of the shield launching/arriving shafts of Metro works in Guangzhou region, the authors presents the major methods and basic requirements of the reinforcement of the shield launching/arriving shafts located in sandy soil ground, as well as the validation modes for the strength and stability of the reinforced ground. Taking the geological conditions of a project as an example, the authors make a checking of the reinforcement effect.
