岩体结构是影响岩石承载力的决定因素

Structure of Rock Mass Is Decisive Factor Influencing Bearing Capacity of Rock

近些年我省高速公路建设不断发展,从丹东至本溪高速公路到丹东至海城、丹东至通化高速公路,这些山区高速公路地质条件和岩性条件都较复杂,涉及到桥涵构造物岩石的允许承载力问题,但是在实际工作中往往受各种客观因素影响,相同条件下,不同单位和不同的工程师所提供的岩石允许承载力和极限侧阻力差异较大,造成了很多浪费。

In recent years, the freeway building in our province is constantly developing, for example Dan-Ben Freeway, Dan-Hai Freeway and Dan-Tong Freeway. The geological conditions and conditions of rock nature of these freeways in mountain area are all relatively complex, involving the allowable beating capacity of rocks for culvert structures. At the same time, the allowable beating capacity and limiting lateral resistance of rock, which are offered by different unit and engineer, are unlike in the same conditions owing to effect of various objective factors, with bigger difference, so causing the much waste.
