The lattice beam and anchor pipe grouting composite structure is an effective engineering measure in landslide control. In this article, the mechanism of lattice beam and anchor pipe grouting was expounded. The effect of anchor pipe on the lattice beam was regarded as concentrated force, and the force was derived from residual thrust method. The lattice beam was regarded as Winkler elastic foundation. The internal force and reinforcement of beam were calculated. According to in-situ grouting experiment, the mix proportion and strengthening area of grout were got. The methods and steps of ancho...
