A　case　study　on　interaction　between　a　landslide　and　nearby　structures　is　researched　in　this　paper.　This　landslide　lead　to　displacement　of　the　foundation　of　electric　power　pylon　located　at　the　top　of　the　landslide　and　deformation　of　the　reinforced　concrete　lining　of　highway　tunnel　located　at　the　toe　of　the　landslide;　further,　it　will　induce　instability　of　abutment　which　will　be　built　at　the　toe　of　the　landslide.　In　the　other　hand,　highway　tunneling　at　the　toe　of　the　slope　and　electric　power　pylon　constructing　at　the　top　of　the　slope　are　proved　to　be　induction　factor　of　the　landslide　disaster.　According　to　the　deformation　behaviour　of　the　landslide　and　nearby　structures,　back-analysis　technique　is　used　to　determine　mechanics　parameter　of　the　landslide　soils,　and　then,　unloading　excavation　and　anchorage　measures　are　carried　out　to　stabilize　this　landslide.　In　the　end,　some　suggestion　is　discussed　for　the　similar　project　reference.　©　2011　IEEE.
