摘　　要：格构梁与锚管注浆复合结构是治理滑坡的一种有效措施,文中系统阐述了格构梁与锚管注浆复合结构的作用机理、格构梁简化为受多个集中力作用的弹性地基梁进行计算的原理与步骤以及锚管注浆加固裂隙岩体的设计实施过程,并将其应用于常张高速公路K129边坡的治理中,取得了满意的结果,可为同类工程提供有意义的参考。The lattice beam and anchor pipe grouting composite structure is an effective engineering measure in landslide control. This paper deals with the mechanism of lattice beam and anchor pipe grouting, the principle and procedure of calculation by simplifying the lattice beam as Winkler elastic foundation, and the design of anchor pipe grouting for application to fractured rock slope reinforcement. As a case study, the lattice beam and anchor pipe grouting was used in control of K129 slope of Changzhang highway and brought about a satisfactory result. This method will prove to be useful to the same engineering.
