The pyroclastic flow deposits formed by the eruption in 1000 BP widely distributed to the south of the Guangming Forest and the rockfall deposits in the upstream of the Erdaobai River provide a source for massive solid loose materials.
After volcanic eruption, plants are not developed in the Erdaobai River Basin, eruptive materials are loose thus branch gullies are easily formed, and fall into the Erdaobai River.

Introduction Beams are categorized by their profile (shape of cross-section), length, and material property.
Much of the material in a beam needs to be positioned as far away from the neutral axis as feasible in order to resist the bending effects in the best possible way.
Linear elastic material with Young’s modulus E = 2.1x105MPa, Poisson’s ratio = 0.3 and density = 7850kg/m3 are used in this study.

Fiber materials currently include steel fibers and polypropylene fibers, each with its advantages and adaptability.
Fiber reinforced concrete is composite material based on mortar or concrete with metal materials, inorganic fibers or reinforcing material.
In the initial stage of load , cement-based materials and fibers bear force in common, which is important to bear by the former.
