Study On Compound Structure Of Reinforcing Concrete Lattice Frame And Anchor In Landslide Protecting

Landslide is a serious geological disaster.Measures for preventing andcontrolling landslide are highly regarded.Lattice framed anchor structure is a newanti-slide retaining measure for protecting slope and retaining stability of landslidetogether .It does not need huge machines in construction and is safe and quick.It isbetter for loosen landslide body.It is a developing anti-slide retaining structure,and thedesign theory and methods need to be improved.All of these are reason of the topicselected to study.The dissertation primarily focuses on the following aspects.(1) Regular framed anchor structures are analyze.Applying conditions offramed anchor structure are presented.Regular patterns of lattice beam are square,diamond,triangle and arch.It isproposed that different material and pattern of framed beams are chosen to landslidecharacteristic.(2) Mechanical model of lattice frame anchor structure is proposed.Designtheory of RC lattice beam is studied by analytic solution of the beam on Winklerelastic foundation quantificationally.(3) 3D finite enement method is used to simulate lattice frame anchor structurewith ANSYS software.Reacted by lattice frame anchor structure,variety regulation ofloose soil layer's stress and deformation was studied.(4) Opitimal design to prestressed anchor cable on lattice frame anchor structureis discussed.Anchoring angle affects force retaining greatly.It is deduced that the anchoringangle of force retaining maximum is not the most economic anchoring angle.The mostopitimal anchoring angle is chosen,according to actual conditions in anti-slidemeasure project.(5) Lattice frame anchor structure is applied to control protect design of a slope.
