摘　　要：以上海地铁10号线盾构隧道的进出口端头井加固为例,说明软土地区盾构端头井基坑的加固方法,重点说明高压旋喷桩和三轴搅拌桩联合加固在软土地区的应用和用FLAC软件对加固后土体进行稳定性分析。表明此种方法在软土盾构端头井加固的设计和施工的实用性,为以后同类工程的设计和施工起到一定的借鉴作用。Taking the reinforcement of import and export end well of shield tunnel on Shanghai Metro Line 10 as an example,the way to reinforce pit of shield end well in the area of soft soil was explained and the application of the high pressure jet grouting piles and three-axis joint reinforcement mixing pile in soft soil area and reinforcement with the FLAC software for stability analysis Houtu body were highlighted,which showed the practicality in soft soil reinforcement shield end well design and construction and provided a reference to the future design and construction of similar projects.
