In order to deeply study the mechanism of prestressed anchor anti-slide pile, an indoor model experimental device was developed, and a finite difference particle flow numerical analysis slope cable pile established based on reinforcement project in mountain road slope. Based force displacement characteristics influence prestress cable, inclination angle width column spacing landslide, height na...

In view of the complex asymmetric deformation characteristics inclined coal seam roadways and tensed shear failure anchor cable supports, support scheme an with a C-shaped tube is proposed. order to study its supporting effect on roadway, this paper first explores difference in performance between through double tests. Then, based roadway Pangpangta Mine, numerical simulation used roadway. The ...

Abstract In order to overcome the technical defects of traditional foundation pit support technology, such as complex serious pollution, waste resources, and obstruction construction surrounding underground structures, fully recovered deep system pressure dispersion anchor cable steel module is designed. The force compression deformation modular tested on-site. test results show that: (1) whole...

This paper presents a methodology to optimize the cable system in cable-stayed bridges, whose main novelty is take into account accidental breakage of one within design process. To this end, multi-model optimization strategy proposed by establishing constraints on both intact and damaged models. The dynamic effect accounted for models application impact loads at tower deck anchorages. objective...

A landslide located in northern Sichuan Province, China was investigated. series of numerical models the stabilized with piles and anchor cable frame beams were developed using a three-dimensional finite-element method. The Strength Reduction Method employed to investigate stability slopes, internal forces piles, axial cables. parametric study consisting pile position, length, spacing carried o...

To research the internal load transfer behavior and failure mechanism of a bird’s nest anchor cable anchoring structure based on pull-out test, bond-slip model is established basis statistical damage theory, distribution formula shear stress at anchorage agent–rock interface deduced. Combined with theoretical analysis, pulling out test particle flow code (PFC) numerical simulation as well axial...

Abstract The prestressed anchor cable can improve the overall stability of rock and soil mass slope, thereby improving mechanical properties mass, better control structural displacement, achieve purpose reducing landslides, dangerous rocks rocks. At same time, pre-stressed construction is convenient, fast in progress, economical, has a broad application space. Based on actual engineering backgr...
