The Effact Research Of Rail Bar In The Dealing With Rock Collapse And Stone Fall Disease

In recent years, setting up rail bar is one of important measures to deal with rock collapse and stone fall nearby roads. As is well known it can keep the fallen rocks out of the road in stead of bulkhead. Generally, rail bar base is made of concrete or grout rubble, then the standing poles are worn rails or concreter poles and the horizontal bars are rails. Compared with bulkhead, rail bar building wants few jobs, little working and few costs in flexible way.In reality, rail bar is applied to some road with nature geology disease successfully and effectively in such as Baocheng rout and Chengkun rout railway. Since rail bar consists mainly of worn rails and belongs to efficiency craft in preventing geology disease with high output and low consumption, it has a far bright applicable prospect.At present, rail bar usually shows along with the built road, whose design and construction are still at the experience accumulating stage. In the text, the most important measures of preventing rock collapse and stone fall are generalized, and the rail bar design principle is discussed, basing on the geology analysis and design process of the rail bar's applicable possibility, correct position, structure pattern, some parts of mechanics characteristic and others.After the possible mechanics characteristic of the rail bar's every part when it is compacted by fallen stones is studied, the design requirements of the rail bar material intensity, the underground foundation dimension and the rail bar structure are analyzed at large. According to the slope modality where rock collapses and stones falls, the fallen stones' moving orbit, the propose position and height size can be ascertained accurately. Further more, the feasibility of this design idea is proved by a proper rail bar design project instance in the text So it makes up the rail bar design theory of remedying rock collapse and stone fall, offering certain important reference to the researches that will be carried on at relevant respects in future.
