摘　　要：土钉式桩间护水平加固技术作为新兴的水平加固技术在工程中应用较少,适用于城区内周边条件复杂的支护结构设计。其对土体的加固使土体的力学参数得到大幅提高,有利于水平支护结构的安全和稳定。但其计算理论仍有待于提高。As an emerging technique, the horizontal strengthening technique among supporting structures of soil-nailing pile is seldom applied in projects, but it is applicable to design of supporting structure under complex peripheral conditions in urban areas. This technique can strengthen the soil and increase the mechanical parameter of soil obviously, so it is applicable to guaranteeing safety and stability of horizontal supporting and protection structure. But calculation theory of this technique needs to be further improved.
