Abstract: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.
