Model Test Studies on Slope Supported by Bamboo Anchor and Timber Frame Beam

In the process of slope protection, it takes some time for the root system of plants to grow. Before the plant root system forms a developed root system, its reinforcement function cannot be exerted, and the stability of the slope cannot be effectively guaranteed. Aiming at the deficiency of plant slope protection technology, a new structural form of combined support of living stumps and bamboo anchors is put forward in this paper. Two groups of slope model tests with or without bamboo anchor and timber frame beam support are established. Through experiments, the variation law of axial force and bending of bamboo anchor under the condition of bamboo anchor and timber frame beam support is summarized, and the influence of the bamboo anchor and timber frame beam support on slope displacement and slope deformation is compared and analyzed. The relevant conclusions are summarized as follows: (1) The bamboo anchor in the slope is a kind of "tension–compression–bending composite member" with tension as the main function. Under the load on the top of the slope, the axial force and bending moment of the anchor on the top of the slope are significantly greater than that of anchors in the middle and toe of the slope. (2) Compared with the slope without bamboo anchor and timber frame beam support, the displacement of the slope with bamboo anchor and timber frame beam support is smaller, which has obvious supporting effect on the middle of slope. (3) The settlement depth on the top of the slope with bamboo anchor and timber frame beam support is less than that of the slope without bamboo anchor and timber frame beam support, and the slope has no obvious sliding phenomenon. Bamboo anchor and timber frame beam structure can also restrain the deformation of the slope to a certain extent.
